Hi, You can find attached the code for transmit and receive sides, and the file which I am sending (send.txt) and one which I am receiving (rcv.txt). You can see that nearly 80%-90% received data is corrupt. I am receiving around 50dBm at receiver antenna, and I have tried with both stations at less than 1 meter. so transmission power can not be the problem. There is nearly zero interference where I am checking it so interference cant be the problem.
If you have two USRP boards and two RFX2400 daughter cards then you can try these codes (fsk_tx.py and fsk_rx.py) using: ./fsk_tx.py send.txt for transmitter ./fsk_tx.py -f rcv.txt for receiver (But dont forget to empty rcv.txt before running this) I'll be thankfull if you can point out the reason.
