The simplest, yet very useful method for detecting a known deterministic signal in additive Gaussian noise is matched filter(MF). 高斯噪声中的已知 确定信号的检测，最为简单而有效的方法是匹配滤波器。
When sampling period is very low or close to ideal case for signal detection in additive Gaussian white noise (AGWN), the detection circuit with matched filter is optimal. 摘要在加性高斯白噪声信号检测中，在采样周期极小或接近理想的情况下，连有匹配滤波器的检测电路是最佳的。
A new feature based on higher order statistics is proposed for the classification of MPSK signals, which is invariant with respect to constellation translation (shift), scale and rotation, and can suppresses the color or white additive Gaussian noise. 针对MPSK信号的分类问题
First,based on the Viterbi algorithm and the Least-mean-square(LMS) algorithm,the computer simulation of digital communication system with ISI and additive Gaussian noise has been made,by means of the adaptive-decision-feedback equalizer. 对AWGN信道下具有串扰的通信系统进行了基于维特比算法和最小均方算法(LMS)自适应判决反馈均衡的计算机仿真.
