摘要
研究了非高斯噪声中具有未知参数的信号的渐进最优检测,应用非高斯噪声中线性模型信号以及随机信号的Rao检验,导出了Rao检测的解析式,并与广义似然比检验的性能做比较。仿真结果表明,该检测器性能大大优于传统的能量检测器和高斯噪声假设下的广义似然比检测器。
Insensible optimal detection method of unknown parameter signal in non - Gaussian noise is introduced. The analytic expression of Rao detection is presented based on the Rao detection of linear signal and random signal in non - Gaussian noise. The character of the detector and preference is given through simulation in computer in compare with the GLRT.
