用matlab产生仿真BOC信号，并对BOC信号采样并用FFT进行频谱分析。-BOC signals generated simulation using matlab, and the BOC signal sampling and spectral analysis using FFT.

对信号加入噪声，绘制频谱图，设计滤波器，对信号进行频谱分析，滤波-The noise signal is added, rendering the spectrum diagram, the design of filters for spectral analysis of the signal, filtering

spectrum.music对象和pmusic函数提供Schmidt提出的MUSIC算法。该算法基于对自相关矩阵的特征分析，用于对频谱的估计。这种谱分析将数据相关矩阵的信息分为信号子空间和噪声子空间。-spectrum.music objects and functions provide MUSIC algorithm pmusic Schmidt raised. The algorithm is based on the correlation matrix of the feature a

在同时存在强信号和背景噪声时，用自适应谱增强器用于谱分析，检测弱信号。本程序利用LMS算法实现了弱信号的检查。-Adaptive spectrum enhancer for spectral analysis
