Two-stage acquisition algorithm for DSSS signal based on compressive sensing

  • 摘要: 针对直接序列扩频(DSSS,Direct Sequence Spread Spectrum)信号的捕获性能与硬件消耗或计算复杂度的相互制约问题,基于压缩感知理论,提出了一种双阶段压缩捕获方法,第1阶段进行快速粗捕获,第2阶段在第1阶段基础上实现精确捕获.首先研究DSSS信号的相关域稀疏性,构造了稀疏变换矩阵;然后利用确定性沃尔什-阿达马矩阵,分别构造了2个阶段压缩测量矩阵及其检测算法;最后从检测概率和平均捕获时间两方面对提出算法的捕获性能进行了理论分析,并用蒙特卡罗法进行了验证.理论分析和仿真实验表明,该方法能够在显著降低相关次数的前提下,达到传统基于并行相关方法的捕获性能水平.
