Notes from – pskmod: Modulate signal using M-PSK method https://au.mathworks.com/help/comm/ref/pskmod.html
The pskmod function performs M-ary Phase Shift Keying (M-PSK) modulation, converting input symbols (X) into a complex baseband signal (Y).
Key Syntax
Y = pskmod(X, M): Modulates input X using modulation order M.Y = pskmod(X, M, phaseoffset): Specifies the constellation’s phase offset (in radians).Y = pskmod(X, M, phaseoffset, symorder): Specifies the symbol mapping order.
data = randi([0 M-1], 1000, 1);
txSig = pskmod(data, M, pi/M);
Adding fading to simulation models a more complex and realistic wireless channel where the signal strength fluctuates. The most common model for fading in non-line-of-sight environments is the Rayleigh fading channel.
