摘要:
讨论了跟踪及数字中继卫星系统(TDRSS)一种新的扩频调制方案,即并行MSK扩频.根据不同的TDRSS业务在I路和Q路根据数据率的高低选择扩频或不扩频.给出了QPSK扩频调制和并行MSK扩频调制的信号表达式和实现模型,并建立了MATILAB仿真模型.理论分析和仿真结果都证实并行MSK扩频调制的频谱特性优于QPSK扩频调制.
Abstract:
A novel spread-spectrum scheme of Tracking and Data Relay Satellite System, i .e . the parallel MSK spread-spectrum modulation is discussed in this paper. According to various TDRSS services spread-spectrum modulation is used or not. The signal equations and the implementation models of QPSK spread-spectrum and parallel MSK spread-spectrum modulation are presented. It is testified that the spectrum efficiency and the rolling drop characteristic of parallel MSK spread-spectrum modulation is superior to QPSK spread-spectrum modulation by the emulation results.
