摘　　要：本文以一类高斯型混合非高斯噪声双模噪声为背景噪声,详细分析了二进制数字调制系统的抗噪声性能。为研究更一般的情形,本文提出了窄带多模过程的数学模型,进行了较详细的研究,给出了混合噪声中信号检测的一般方法,是对原建立在高斯噪声基础上通信与信号处理理论的完善和补充,有一定的普遍意义。在理论分析的基础上,最后给出了仿真结果并进行了分析。The noise performance in binary digital modulation system is analysed in the presence of gaussian hybrid additive white bimodal noise.The mathematical model of narrowband multi-model process is put forward for studying more general circumstance.At the same time a general algorithm for signal detection in hybrid noise environment is presented. It has some general significance and is the perfection and supplement of the theory of communication and signal processing based on Gaussian noise. On the basis of theoretical analysis,simulation results are given and analysed.
