  7. In this paper, bit - error rate performance analyses are presented for coded and un - coded frequency hopping m - ary frequency - shift keyed systems under the condition of additive white gaussian noise ( awgn ) and partial band noise jamming and multitone jamming. the use of error - correct codes provide a way to improve the performance of frequency hopping system, particularly the use of reed - solomon code in a fh system under the condition of partial band noise jamming can greatly improve the performance of system. so we provide the way of coding and decoding of rs code in c language. in the end, we offer the simulation of the performance of time diversity fh / 2fsk system over partial band jamming noise channels
