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
works fine but the receiver hangs!!
I do the upconversion on transmitter after modulating, and transmit. and
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)
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
means the packets received are not in proper format! Wr can i possibly
going wrong? I am stuck here and any suggestion will be of great help!
