• 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
  第一章为绪论，叙述跳频通信的发展趋势，以及基本概念，第二章及第三章介绍提高抗部分频带干扰的前向纠错码reed - solomon码的原理和实现方法。第四章研究跳频通信系统在各种干扰条件下的性能。最后在第五章以fh mfsk系统为例，探讨在部分频带干扰下的系统性能，并进行计算机仿真，仿真结果表明采用分集技术和各种编码技术对于系统的性能改善具有明显的效果。
