HW1_Part1

M ary psk modulation and demodulation

说明：  本程序是对语音信号去除噪声。MATLAB编写(This procedure is a speech signal to remove noise. MATLAB prepared)

此程序能够很好的实现调频调相调幅等多种调制方式和多进制的调制。(This process can achieve the frequency modulation and amplitude modulation and other multi-band modulation.)

An Active Rectifier must be installed in a 60Hz 208V three-phase distribution system in order to provide a high power quality 600V DC supply for a 150kW motor drive. The active rectifier VSC and control is an American Superconductor (AMSC) PM-1000 Power Module with the Active Rectifier control option.

overlap addition for input sequence long

说明：  基于MATLAB的dv-hop（distance vector routing）算法的实现(Based on MATLAB-dv-hop (distance vector routing) Algorithm)

包含了一个蚂蚁算法中的蚁密系统，程序运行良好！(Contains a dense ant ant algorithm in the system, run good!)

AM_SSB_Modulation Techniques

基于matlab的非线性方程二分法迭代求解（GUI）(bisection method)

求波形的峰值，可以求出一组数据中的峰值，并且数据的峰值可以有很多个。(Seeking the peak of a waveform, can be calculated in a set of data in the peak, and the data of the peak there can be many。)
