说明：  采用Coif小波变换在matlAB中对信号进行压缩降噪处理并进行比较(Wavelet transform using Coif matlAB compress the signal in the noise reduction and compared)

说明：  直线偏移代码，已知多边形顶点坐标，可以将多边形各边沿其法线方向平移距离然后得到新的多边形顶点。(Linear shift code, known polygon vertex coordinates, can be the edge of the polygon shift its normal direction and then get a new polygon from the vertex.)

Adaptive filtering constitutes one of the core technologies in digital signal processing and finds numerous application areas in science as well as in industry. Adaptive filtering techniques are used in a wide range of applications, including echo cancellation, adaptive equalization, adaptive noise cancellation, and adaptive beamforming. Acoustic echo cancellation is a common occurrence in today’s telecommunication systems. The signal interference caused by acoustic echo is distracting to users and causes a reduction in the quality of the communication. This paper focuses on the use of LMS and NLMS algorithms to reduce this unwanted echo, thus increasing communication quality.
