[Discuss-gnuradio] Overflow problem using multi-antennas

2010-06-01 Thread Hassaan Ajaz
Hi I have implemented multi-antennas for receiving using grc dual source but when i set the bitrate above 1M it start displaying "Uo Uo" which i guess is indication of overflow and it doesn't receive anything also. I am using usrp1 with rfx2400 daughter card. Kindly help me with my problem. __

Hi I am trying to develop physical layer for cooperative MIMO wireless system. I have used benchmark (gmsk) as the base platform and trying to bring about changes in it. I have made the packet size of 10 bytes 2 for packet number and 8 for data from a certain file for transmission. Now in order to
