ERROR PERFORMANCE ANALYSIS OF FFH MFSK SYSTEMS WITH MULTITONE JAMMING/

This paper presents a new approach to computing symbol error probabili ty-of fast frequency-hopped M-ary frequency shift keying (FFH/MFSK) sy stems with majority vote under multitone jamming. For illustrating the applications, we first consider the case in which the source data rat e is fixed and the hopping rate is allowed to vary. In this case, the optimum orders of diversity for several values of M are examined. Resu lts show that M = 4 outperforms other values. Then, we treat another c ase in which the hopping rate is fixed and the data rate is adjusted s o as to obtain maximum throughput under a given constraint of error pr obability. In addition to the case of diversity alone, we also evaluat e the performances of the fixed hopping rate case with channel coding using convolutional code and BCH code.
