Thanks Marcus. given parameters : bit rate = 100,000 samples per symbol = 2 constellation = 16 then, bits per symbol = log2(16) = 4 symbol rate = bit rate / bits per symbol = 100,000 / 4 = 25,000 sample rate = samples per symbol * symbol rate = 2 * 25,000 = 50,000 also, as I know, sample rate =

Hi, > I think it is up to bit rate, but I don't know exactly what it is. 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). > Is there unlimited bit rate option for check to

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

2016-03-01 Thread SangHyuk Kim
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
