中文摘要：
针对跳频信号能量检测法中遇到的问题,论文设计推导了一种基于能量谱和双谱的融合检测算法。该方法通过融合能量谱法得到观测信号的二阶统计信息和双谱法得到的三阶统计信息,分析可利用的检测信息,从而完成对跳频信号的盲检测。仿真结果表明,不管是在高斯信道还是瑞利衰落信道等环境下,该文算法相比能量检测法和双谱法都具有更好的性能。并且数据越长的信号,其检测性能越好。
英文摘要：
To deal with the problem in energy detection algorithm of FH signal,a fusion detection algorithm is introduced based on energy spectrum and bispectrum.Based on analyzing the second-order statics through energy spectrum and third-order statics through bispectrum,the algorithm realizes the detection of FH signal.Simulation results indicate that the algorithm has a better performance than energy detection algorithm and bispectrum detection algorithm in Gauss channel or Rayleigh channel and that the detection performance is better,when the data is longer.
