Hi I wanted to do the benchmark tx and rx with Audio instead of the USRP. I made all the changes to the transmitter and the receiver. The transmitter works fine but the receiver hangs!!
I do the upconversion on transmitter after modulating, and transmit. and do the downconversion on receiver side before demodulating. Upconversion : I multiply by a sine wave Downconversion : I multiply by both sine and cos, (which make I and Q) and use a float_to_complex to make them into one complex stream. I set the converter rate = sample rate = 18000 frequency = 250 Hz interp_deci_rate = 200 Bit rate comes to 45 when samples_per_symbol = 2 I guess the hanging is at the delete_head() stage of the pkt.py! That just means the packets received are not in proper format! Wr can i possibly be going wrong? I am stuck here and any suggestion will be of great help!
