Noncoherent Detection of FSK Signals in the Presence of Multipath Fading

The performance of a noncoherent frequency-shift keyed (FSK) system is analyzed in the presence of multipath fading by using a sinusoidal series expansion technique for the representation of a bandlimited Gasussian process. The probability of error is calculated as a function of the system parameter
BT
, signal-to-noise ratio, fading bandwidth and direct to reflected signal power ratio.
