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/[1]/ 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.
