| 摘 要： | 分析了串行MSK DS/SSMA系统的性能。这种单通道系统能够产生和并行双通道MSK DS/SSMA系统相同的发射信号,它具有恒包络和优良的频谱特性。而且,串行MSK DS/SSMA系统的硬件成本和BPSK DS/SSMA系统的相当,分析结果表明,前者的性能更优。

| Abstract: | The performance of serial MSK DS/SSMA communication systems is analyzed in this paper.This single-channel system can generate the same transmitted signals as a corresponding parallel two-channel MSK DS/SSMA system,and the transmitted signals have a constant envelope and desirable spectral properties.Moreover,the hardware cost of serial MSK DS/SSMA system is comparable to the cost of BPSK DS/SSMA system,and the results of analysis indicate that the former can achieve better performance. |
