AD9361 I/Q channels can't be configured individually, then how to use just one channel to send and reveive BPSK signal?
AD9361 uses IQ modulator and IQ demodulators. For Tx you need to write the data in IQ format and similarly Rx received data will be available in IQ format. There are many resources available online for BPSK communication systems.
Since the TX data samples are in two’s complement format;for TX, all you need to do is always feed all 0’s to the Q input. The I inputshould go from + Full Scale to – Full Scale.
On RX, without phase recovery, the data will be on both Iand Q; tlili is correct in pointing out thereare many references on what to do with this. What seems like a fairlystraightforward on is:
The most positive sample value is 0x7FF and the most negative value is 0x800
