Re: [Discuss-gnuradio] benchmark_tx(rx).py throughput as modulation

The number of bit per second you're going to be transmitting/receiving. It's (symbol rate) *  (bits per symbol). "bits per symbol" is of course log2(constellation points).

No, a given modulation with a given sample rate and a given samples per second must result in a fixed transmission rate.

Best regards,

Hi all.

I'm using benchmark_tx.py and rx (/digital/example/narrowband)

As I know, ex) QAM modulation is faster than BPSK one.

However, when I used both of modulation schemes, I couldn't measure throughput.

I think it is up to bit rate, but I don't know exactly what it is.

Is there unlimited bit rate option for check to modulation throughput ?

Thanks.
