对802.11a系统的信道估计技术进行研究，提出了基于迭代估计的算法(Of the 802.11a system to study the channel estimation technique is proposed based on iterative estimation algorithm)

矢量网络分析仪的驱动程序，可以用matlab调用(Vector network analyzer driver, you can use matlab call)

OFDM系统信道估计算法MATLAB实现，基于信噪比和误码率对LS、MMSE算法进行性能对比。(OFDM channel estimation algorithm MATLAB system, based on the signal to noise ratio and bit error rate performance comparison of LS, MMSE algorithm.)

说明：  运用matlab进行模糊聚类分析步骤如下：建立数据矩阵；数据标准化；建立模糊相似矩阵；改造相似关系为等价关系；确定分类数(The steps of using MATLAB to carry out fuzzy clustering analysis are as follows: establishing data matrix; standardizing data; establishing fuzzy similarity matrix; transforming similarity relation into equivalent relation; determining classification number.)

局部放电试验所采集的信号中往往混有白噪声、周期干扰信号去除。此处采用常用db系列小波中的db6小波进行9尺度的多分辨分解后，根据白噪声能量特性，估算各尺度的阈值大小，采用硬值进行处理，后进行重构。(Partial discharge test of the signal collected is often mixed with white noise, periodic interference signal removal. Here the use of commonly used wavelet db Series DB6 wavelet carried out in the 9-scale multiresolution decomposition, based on the energy characteristics of white noise to estimate the scale threshold size, the use of hard-value deal, after the remodeling.)
