Dear ALL

for example we use qpsk modulation and 1M sample rate, 

what is the transmission throughput? data rate

You're going to have to decide what *symbol rate* want, and whether the resulting signal bandwidth fits into your 1M sample rate.

Simple QPSK carries two bits/symbol.

Do some research on the bandwidth occupied by a QPSK signal at a given symbol rate, and then use your stated 1M sample rate to see
  how much you can "fit in" to a 1M sample rate.

Your question is more about signals, signal processing, and their properties in the time and frequency domain which is quite independent from
  which signal processing framework you're using.

I encourage you to do some research.
