A is the performance of an optimal coherent demodulator for, Ask an Expert

Engineering

a. Is the performance of an optimal coherent demodulator for M-ary orthogonal signaling affected by amplitude variations in the received signal (slow variations compared to the symbol duration)? Does the answer depend on whether the variations are known to the demodulator? Explain.

b. Repeat for a noncoherent demodulator.
