Abstract

A performance analysis of a slow frequency-hopped, noncoherent binary frequency-shift keying (SFH/NCBFSK) communication system with rate ½ convolutional coding and soft decision Viterbi decoding in the presence of partial-band noise jamming is performed. The effect of additive white Gaussian noise is also considered. The system´s performance is severely degraded by partial-band noise jamming. By way of comparison, a system that utilizes hard decision Viterbi decoding and for a system utilizing noise normalized combining with soft decision Viterbi decoding are examined. In both cases a significant increase in the system´s immunity to the effects of partial-band noise jamming is achieved
