雷达/声纳正处理，常规巴特利特波束形成仿真。假设入射信号角度正横方向，M元接收阵对接收信号进行正负九十度的扫描。(Conventional beamforming for RADAR/SONAR. The source is supposed to be the broadband. there are M element array using for receiving.)

MATLAB implementation of the 3GPP Spatial Channel Model

matlab的四元数工具包，可以进行计算。(The quaternion toolbox is written by Matlab, which can do caculation)

说明：  做地震数据处理的去噪程序，通过原始信号，加噪声的信号，以及小波变换的信号进行比较分析，并生成图像。(Do the denoising program of seismic data processing, compare and analyze the original signal, noise signal and wavelet transform signal, and generate the image.)

This an adaptive receiver for a direct-sequence spread spectrum (DS-SS) system over an AWGN channel. The adaptive receiver block is modified from the LMS adaptive filter block in DSP Blockset. For DS-SS signal reception, the adaptive filter needs to have multi-rate operation. The input sample rate is equal to chip rate and the output is at symbol rate. Two rates are related by PG, processing gain
