摘要

采用最优分集的快速跳频、非相干移频键控(NCMFSK)技术,研究了各种纠错码在最坏情况下的部分频带噪声干扰和最坏情况下的多音干扰性能。给出了一些纠错码的误码率性能,这是对先前发表的研究结果的补充。识别出具有较好抗干扰性能的候选码。综上所述,具有8行FSK的(255,241)Reed-Solomon外码与半正交卷积内码的级联具有最好的性能。如果只考虑非连接代码,则速率1/2 Trumpis代码是最好的,并且仅比最佳连接代码差0.89 dB。

Coding for fast frequency hopped noncoherent MFSK spread spectrum communications under worst case jamming
The authors examine the performance of various types of error correcting codes under worst-case partial band noise jamming and worst-case multitone jamming using fast frequency-hopped, noncoherent M-ary frequency-shift-keying (NCMFSK) with optimum diversity. The bit-error-rate performance of some error correcting codes, which augments the results previously published on the subject, is given. New candidate codes with superior antijam performance are identified. It is concluded that, overall, the concatenated (255,241) Reed-Solomon outer code with the semiorthogonal convolutional inner code with 8-ary FSK has the best performance. If only nonconcatenated codes are considered, the rate 1/2 Trumpis code is best, and is only 0.89 dB worse than the best concatenated code.<>
