This MATLAB function modulates the input signal using differential phase shift keying (DPSK) with modulation order M.
Create an error rate calculator. Set theComputationDelayproperty to1to account for the one bit transient caused by the differential modulation. errorRate = comm.ErrorRate(ComputationDelay=1); Run a loop processing frames of data that consists of these main steps: ...
