摘要 以实现卫星认知无线通信中频谱空穴探测为目的,列举并比较了目前用于频谱感知的六种算法。根据各个算法的自身特点指出其应用场合,分别分析了它们的优缺点,通过计算机仿真给出了能量检测、匹配滤波和压缩感知的检测性能,并指出压缩感知对硬件复杂度的要求最小,适合卫星认知无线通信。 To achieve spectrtum methodologies are introduced and holes detection in cognitive satellite communication, six spectrum sensing compared. According to their characteristics, the application of each method and the analysis of advantages and disadvantages are presented. Computer simulation results show the performances of energy detection, match filtering and compressed sensing. It is pointed out that compressed sensing is suitable for satellite communication because of minimum hardware complexity.
