Questions about dqpsk, dbpsk

GNU Radio
1

Hello for All,

I use the benchmark_tx.py and benchmark_rx.py located in /digital. I use
the diffirent examples of modulations and demodulations, and I have some
remarks.

  1. when I use dbps, d8psk in demodulation/modulation some pkt are losted
    and an others with False indication. It’s normal to have this result?

  2. When I use GMSK and DQPSK all packets are received but the last one
    is with a False indicator. Can you tell me why?

Best regards.
