Given a received signal samples, the objective is to determine the modulation scheme that is present in the signal and demodulate data if required.

Example : Assume that we know that the received signal contains one of the two schemes BPSK or QPSK in the presence of noise. The problem is to say which is present. How to go on with this problem statement. What will be the good solutions.
