Wide-Band Detection of FSK Transmissions in a Three-Component-Two-Path Channel

The multipath model evaluated is of a three-component-two-path type. In several space channels we have a directtransmission path and a reflected-transmission path. The direct component can be described as specular, while the reflection is a composition of both a specular component and one that is diffuse. The channel bit error probability for noncoherent wide-band frequency-shift keying (FSK) is obtained for such channels. It is shown that parameters such as rate of fade, Doppler, and data rate relative to the delay between the two transmission paths affects the system performance significantly.
