摘要
信号检测是双模噪声中的主要问题之一,本文对此进行了较完整的研究。混合噪声中信号的检测比高斯噪声中信号的检测复杂,可能为多门限判决。本文对不同情况给出了不同的最佳检测方法,并分析了它们的性能;通过对窄带双模过程的研究,给出了混合噪声中信号检测的一般方法,有一定的普遍意义。
The detection of signals from bimodal noise is studied comprehensively.Detection of signals in hybrid noise environment is more complicated than that in Gaussian noise only.It involves multi-threshold judgement.For this reason,different optimization algorithms of detection are proposed to suit different conditions.Their respective performances are also analyzed.Based on the investigation fo narrow-band bimodal process,an algorithm for signal detection in hybrid noise environment is presented.It has universal application significance.
