此程序实现了一种改进的ofdm下的信道估计方法，综合了以往的几种内插方法，并加以改进-This program realise a new channel estimation beneath the ofdm system combining several former intersecting method.Furthermore, certain ameliorations are also being done.

用小波变换思想,提出一种基于小波去噪的多输入多输出正交频分复用(MIMO-OFDM)系统信道估计方法。该方法首先利用最小二乘(LS)方法进行信道估计,然后对估计后的结果进行小波去噪处理。与传统最小二乘信道估计方法相比,该方法不需要预先知道信道的统计特性,信道估计性能有明显提高。-Based on wavelet transform,a method for MIMO-OFDM channel estimation with noise reduction is given,which is di

Frequency Synchronization in OFDM System An accurate frequency synchronization method using the zadoff-chu (ZC) constant envelop preamble is analyzed, and a new preamble weighted by pseudo-noise sequence is used for orthogonal frequency division mu
