| 摘 要： | 在对部分带宽噪声干扰、多址干扰和高斯白噪声干扰情况下的MFSK调制异步非相干混合DS-SFH扩频通信系统性能分析的基础上，对使用RS(N，K)码、双点卷积码和级联码(RS(N，K)码外码、双点卷积码内码)等前向纠错信道编码的MFSK调制异步非相干混合DS-SFH扩频通信系统性能(没有信道付信息情况下)进行了分析、比较；同时对部分带宽噪声干扰对混合扩频通信系统的影响进行了讨论和分析，并给出了各种编码情况下的系统误码率与部分带宽噪声干扰参数ρ之间的关系曲线。

| Abstract: | In this paper, firstly we analysis the performance of MFSK modulation asynchronous noncoherent hybrid DS-SFH spread spectrum communication systems with partial band noise, multiple access interference and AWGN, secondly we analysis and compare the performance of MFSK modulation asynchronous noncoherent hybrid DS-SFH spread spectrum communication systems which employ forward-error-control coding, the coding schemes which we analyze include: Reed-Solomon codes (error-only decoding), dual-k convolution codes, and concatenated codes (Reed-Solomon outer codes with dual-k convolution inner codes). At the same time, the effects of partial band interference on the hybrid spread spectrum system performance is discussed and analyzed, and the bit error probability of coded hybrid system as a function of p, the fraction of band which is jammed, is derived. |
