Multitone jamming of FH/BFSK in Rician channels

A new bit error rate (BER) expression for a noncoherent frequency-hopped bi nary-frequency-shift-keying (FH/BFSK) receiver in Rician channels, subjecte d to independent multitone and wideband noise interference, is derived. Unl ike previously published analyzes, we combine the signal and jammer multipa th components, the additive white Gaussian noise (AWGN), and other wideband interference as a single Gaussian process. This method leads to a BER expr ession which consists of only a single rather than a triple integral requir ing numerical computation. We also present a new derivation of the probabil ity density function (PDF) of the ratio of two Rician random variables; use d in a previously published approximate BER analysis.
