The square-law detector in FHSS BFSK systems and its performance characteristics in impulsive environment

In this paper, the noncoherent reception performance of frequency hopping spread spectrum communication systems operated in channels with impulsive noise and selective multipath fading characteristics is investigated. Binary frequency shift keying modulation and noncoherent demodulation are assumed and squarers are used to detect signals. The bit error rates are obtained as functions of channel and system parameters.<>
