I am running my codes in basic TX/RX with gnuradio-3.3.0 image. I am
benchmark_tx and benchmark_rx codes in the
folder to find packet loss for different modulation schemes (I believe
these files have been transferred to the gr-digital/examples/narrowband
folder in the new image). When I run my the benchmark codes with dbpsk
dqpsk modulation, the receiver receives packets. However, when I run the
codes with d8psk modulation scheme, the receiver just sits idle waiting
the packets but does not receive anything !
I am giving the following commands in the benchmark programs:
./benchmark_tx.py -f 2.4G -r 1M -e eth2 -m d8psk --tx-ampl 0.5
./benchmark_rx.py -f 2.4G -r 1M -e eth2 -m d8psk
I am getting the following packet reception ratios for different
dbpsk: 99%, dqpsk: 92%, d8psk: 0% !!
I expected to get less packets (higher packet loss) through d8psk
since it is transmitting at a higher data rate. But the receiver is not
receiving anything at all !!
Your feedback will be highly appreciated.
