[Discuss-gnuradio] Simultaneous RX/TX using RFX2400 Boards.

[Tarun Tiwari]

Hi,

I have written a code for simultaneous TX/RX for RFX2400 as followed below:





self.rx = usrp.source_c (0,self.decim)
self.tx = usrp.sink_c (0, self.interp)
.
.
.
fg = my_graph() 
.
.
.
fg.subdev.set_enable(True)                       # Enable transmitter
fg.connect(fg.rx, fg.tx)
.
.
.

When I receive and then transmit, the waveform distortiton is
very high on transmit path. I used different combination for decimation
and interpolation rates, but that didn't work. 

I am recieving a sinusoid wave using RX2 port on 2.40GHz and transmitting using TX/RX port on 2.48GHz.

Can somebody tell me about the reason for distortion?

Thanks in advance.
