Abstract :
An error probability analysis is performed for a conventional M-ary orthogonal frequency-shift keying (MFSK) noncoherent receiver employing fast frequency-hopped spread-spectrum waveforms transmitted over a Rician fading channel with partial-band interference. The partial-band interference is modeled as a Gaussian process. As might be expected, higher modulation orders and greater diversity improve overall system performance when only wideband interference is encountered. However, the performance of the conventional receiver is found to be significantly degraded by worst-case partial-band interference regardless of the modulation order or number of hops per data symbol used for all channel conditions
