.fh / Mfsk System Performance And Rs Encoding And Decoding

Over the past few decades, frequency-hopping (FH) communication system is widely used in military applications for its well performance. But FH systems are used primarily in anti-jam projection, where many users share a common bandwidth, and this may result in degrading in performance of FH system.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.
