This MATLAB function returns the complex envelope of the modulation of the input message signal, x, using PAM and the alphabet size, M.
Demodulate a noisy pulse amplitude modulated signal of order 8. Get M = 8; dataIn = randi([0 M-1],1000,1); Apply pulse amplitude modulation (PAM) to the generated data. Employ a Gray-coded symbol mapping order for the modulation. Get modData = pammod(dataIn,M,0,"gray"); Pass...

Generally, in the IPM scheme, noise can appear on both amplitude and timing of the modulated waveform. As it is the case for other pulse-based modulation schemes, rather large amplitude noise can possibly lead to logic level detection error on the receiver side. However, similar to other an...
