Fading margin can be defined as the incremental Eb/N0, in decibels, required to provide a certain desired error probability in a fading channel as could be achieved with the same modulation technique in a nonfading channel. Assume that a bit-error probability of 10-3 is specified. Find the fading margin required for the following cases:
(a) BPSK,
(b) DPSK,
(c) coherent FSK, and
(d) non-coherent FSK.
