Re: [Discuss-gnuradio] ALOHA, ARQ and simple PHY on GNU Radio

[Ahmed Majeed Khan]

Hi guys,
Sorry for the missing reference in last email. As per following:

We have implemented a simple transceiver chain including an ALOHA based
MAC and send-and-wait ARQ protocol. We have tested the system on two cross  linked USRP boards (cable baseband transmission so far). The source code is available on http://wwwcs.upb.de/cs/gsr.html and might  be interesting to those working on communication networks. Maybe also our  FEC, CRC and framing blocks will be useful for someone. There is also a technical report providing results, more details and  discussing some problems which we found by using GNU Radio in our  environment. 
The source code is far from beeing complete. So feel free to improve it
and do not mind to contact me. 
Cheers,
Stefan Valentin.

I tried installing the module from source code but got following error:

Holger/Stefan, can you please help me rectify it.

>From GNU Radio wiki, I see that Tarun encountered errors in same file; 'gr_convolution_dec.cc'. Tarun, were you able to solve that?

Any idea guys?? Thanks in advance.
