DSD improvements I am working on

Ed_F · Mar 17, 2014

No, I didn't. A number of reasons, the main is the copyright issue with the mbelib library. I rather keep DSD independent as much as possible of mbelib so this can be replaced easily by a different vocoder. Some people might need this.
The code could be refactored so there would be a library with all the FEC implementations and both mbelib and DSD will depend upon it.
You will find easy to replace the Golay24 implementation by something else. I made an effort to document the code and include unit test cases.

Hello,

I have been busy with my real job, but finally got started and setup an account on githib. I forked the dsd repository and even committed a small addition, ALSA support. ALSA support makes it easier to run dsd on newer Linux distributions. padsp is no longer needed. I submitted a pull request so hopefully the changes will make it back to the main program.

Eric- If you have the time, could you also submit the NXDN trunking sync patch (I think you posted it in December) as a pull request?

Thanks,
groovy

Is there a way to allow analogue voice to pass thru dsd+ 1.7 on a system with mixed digital and analogue? If not can you add it?

Unitrunker told me on another post he might look into adding another audio pipe but I don't know. I really really would like to be able to listen to both because I live in tornado alley and the county storm chasers have a talk group (analogue voice) on this system. Also Airport security uses analogue most of the time and provoice some of the time at my city's airport. Unitrunker for now only supports one audio pipe (at least I think it does...)

On another note on DSD+ I found best decodes with using these parameters in a shortcut "C:\Program Files\UniTrunker\DSD\dsd.exe" -dr0 -dh0 -u1 -fp -O NUL

For those wondering why I turned off saving the wav file (DSD+ readme calls it a mp3 but its extension is .wav when you look into the dsd+ folder) I just did it because I have no purpose for a growing .wav file. All the radio traffic I hear is confidential.

Wrong DSD. Eric is referring to the Linux based DSD, not DSD+. DSD+ is a private Windows-based fork of DSD.

I have terrible times with Linux! Okay I just be quiet on this one. Sorry for interrupting

EricCottrell · May 6, 2014

Hello,

I looked at the my NXDN code changes last night. I added code to decode one of the data fields that indicates the type of channel (Trunk Control, Trunk Traffic, Conventional, Composite). Composite is used on Icom's trunked system (Type D) as both voice and trunking control data are sent. More work needs to be done.

Over the weekend I bought a Hytera VHF Analog/DMR radio for use on the local ham DMR repeaters. I also have the local Water & Sewer department as a receive only DMR channel. Setup and using the radio has helped increase my understanding of DMR. I am thinking of getting a Icom IDAS radio as well, although most ham NXDN activity is on the South Shore.

I was surprised to see a listing for a local repeater that supports Yaesu's version of Digital Radio. I hope to capture some transmissions and see if I can figure it out.

Hello,

Recently I started a DMRECC branch on my dsd repository. I am slowly adding DMR error correction and decoding. Today I added additional NXDN sync types to sync up with both Kenwood (Type-C) and Icom IDAS (Type-D) systems.

Currently the DMR code will error correct and decode the CACH, EMB, and Slot Type. This gives some information such as Color Code, Voice Talkgroup, Voice Radio ID, and Mototurbo Connect Plus/Capacity Plus information like network id and site id..

The Respository is on GitHub at LinuxSheeple-E/dsd.

Has anyone successfully compiled & installed this latest release? I went thru the motions and all seemed to go well... but it doesn't seem to actually install. Keep in mind I am nowhere even near being any sort of fluent in Linux which is likely a big contributing factor.

deboe · Jun 10, 2014

Yes, just tried and it built fine.

If you want to share the errors you got, I am sure someone might be able point you in the right direction.

Thanks for sharing that... I didn't get any errors but it doesn't look like it installed. I was using a bootable USB distro though which may be the culprit.

EricCottrell · Jun 11, 2014

Hello,

What additional features you get depends on what branch in my repository you get.

Building from my master branch will only add ALSA support. This appears superseded by the Portaudio support recently added upstream. I need to test this out.

My Feature/DMRECC branch has the ALSA support, plus additional decoding of DMR and additional NXDN syncs. Besides doing some error detection/correction for DMR, it also decodes the CACH (SLCO) and EMB (FLCO). This limited decode does give some useful information like Connect Plus Network/Site/Channel Type, and Talkgroup/RadioID. I am currently working on decoding the CSBK.

Hello from France

I'm a little confuse with EricCottrell software source
is this line below the official source :

https://github.com/LinuxSheeple-E/dsd dsd_eric ?

What is the difference between the 2 sources in the GIT ?

dsd and szechyjs/dsd

thanks for answer

deboe · Jun 17, 2014

Eric made some changes and was just giving people a heads up if they want to try them.
if they work then most likely he will submit a pull request to szechjs/dsd project to be included.

Eric- I looked over what you did but haven't had a chance to build it- it looks very nice.

Just thinking over where the next places to go, I can think of a few things. A few of these I'm qualified to work on, but not many:

1) (Large effort) Move to integer math and table-based trig functions. This is one of the performance bottlenecks in the application.
2) (Large effort) implement stereo output and simultaneous decoding of DMR timeslots (as in DSD+)
3) (Medium effort) convert +48... +48... strol-base2 to bit shifting. Performance improvement and easier to read IMHO.
4) (Medium effort) Implement Yaesu system fusion decoding for v/d mode, perhaps voice/extra ECC mode as well. High rate voice would be a large effort because MBElib doesn't have a AMBE+2 7200bps codec.
5) (Medium effort) Record to mp3 or opus files or whatnot. (as in DSD+)
6) (Medium to large effort) AOR ARD9800/ARD9000 decoding. I think this uses the same codec as D-STAR, but a completely different modem.

Any other items on the hitlist?

EricCottrell · Jun 22, 2014

Hello,

Some of those ideas, and additional ones I have, require major changes and restructuring of code.

The math and trig functions would be more a bottleneck for embedded processors without floating point. I think the problem is all the calculations done to detect and decode QPSK, which I think is dubious when using discriminator output to begin with. I would put in the moving average filter specified in the P25 specifications.

The demodulator leaves out filters so it can detect different modulation types. This affects weak signal performance. Also the wrong modulation optimizations get selected on signals. I really think the audio input should be split into separate decode streams. The program could then detect Provoice and Narrowband NXDN. Some filtering can be shared as Wideband NXDN and DMR are both Four-level FSK with the same filter. I need to run some experiments to see if this can be done on slower processors.

The frame sync code has to change to decode two voice slots. The current code stays in the DMR Voice code during a voice superframe. This would have to be change so the frame sync code recognizes it is in a voice superframe and not to look for voice sync.

Connect Plus Voice Transmission with voice transmission ending on both slots, then a voice transmission by radio 8021 on Group 136 using slot one. One great feature of Connect Plus is the CACH has the Network ID and Site ID so you know the system.

So perhaps someone with a bit more linux experience can help ....

I needed to install libsndfile1-dev and libitpp-dev in order to progress the cmake ../ step listed above

Then when I get to the make step, I get errors:

jim@ubuntu:~/src/dsd-master/dsd_eric/build$ make

make[2]: *** [CMakeFiles/dsd.dir/p25p1_check_nid.cpp.o] Error 1
make[1]: *** [CMakeFiles/dsd.dir/all] Error 2
make: *** [all] Error 2

Anyone got any ideas?

TIA,

Jim

The issue looks to be with ITPP. It might not have installed properly or the version is too old.
It needs to be 4.3 or greater.
Try

Code:

dpkg -s libitpp-dev

to see what version you have.
If its an older version you might need to install from source.

racingfan360 · Jun 25, 2014

ok thanks ...so I was running 4.0 not 4.3. But I'm running on Ubuntu 10.04 Lucid (to maintain compatibility with the original DSD, and I don't really want to upgrade to 12.04 and hit all the issues described elsewhere). To update to itpp-dev 4.3 I need cmake 2.8.6 or higher that doesn't look to be available on 10.04. Very frustrating.

Jim

DSD improvements I am working on
