Hi all.
I'm using benchmark_tx(rx).py example
I experimented variety modulation schemes and GMSK, BPSK, QPSK modulation worked well
However, when I used QAM modulation, most of received packet were corrupted (FALSE)
ENV)
both TX and RX uses USRP N210 with ANT500 and CBX 40MHz
distance between TX and RX is shorter than 3m
TX)
./benchmark_tx.py -f 1.5G -m qam -S 8 --tx-gain=30
RX)
./benchmark_rx.py -f 1.5G -m qam -S 8
RESULTS ON RX)
ok = FALSE pktno = 1 n_rcvd = 1 n_right = 0
ok = FALSE pktno = 2 n_rcvd = 2 n_right = 0
ok = FALSE pktno = 3 n_rcvd = 3 n_right = 0
...
ok = TRUE pktno = N n_rcvd = N n_right = 1
...
Is this normal case of qam modulation ?
How can I get more TRUE packet using QAM modulation ?
Thanks.
