级联MUSIC算法将二维谱峰搜索变为一维谱峰搜索，大大降低算法复杂度。(Cascade MUSIC algorithm to two-dimensional spectrum peak search into a one-dimensional spectrum peak search, greatly reduce the complexity of the algorithm.)

从经典功率谱估计周期图法原理入手，从理论上分析了其存在的局限性，借助Welch算法对其进行修正。依靠Matlab强大的数值分析和信号处理能力，进行实验仿真，比较不同的窗函数，不同的数据长度对Welch法谱估计质量的影响，并分析了造成这些影响的原因。(The paper mainly introduces the principles of Periodogram method of classical PSD estimation,analyzes the deficiency of Periodogram method in theory,and makes use of Welch to amend Perodogram method. By the use of simulation in Matlab, the impacts of different window function and different lenghth of data on estimation quality of Welch are discussed and the reasons of the impacts are analyzed.)

my_2bpsk.rar文件包含了一个m文件和一个低通滤波器数据文件，实现的数字通信系统的升余弦基带成型，bpsk数字调制，以及高斯白噪声、接收端相干解调系统处理的各个阶段，并用plot语句画出了相关波形,对于理解数字通信系统有很大的好处。(my_2bpsk.rar file contains an m file and a low-pass filter data file, to achieve the digital communication system raised cosine baseband shaping, bpsk digital modulation, and Gaussian white noise, the receiver coherent detection system at all stages of processing and used to draw the relevant waveform plot statement, the understanding of digital communication systems is highly desirable.)
