说明：   在MATLAB中开发的最速梯度法算例(in MATLAB development of the steepest gradient method counting cases)

说明：  Matlab demonstration script for DSB-AM modulation.

ADO查询获取的结果输出followind datastruct： myOutput.data myOutput.columnnames 第一个包含一个二维细胞矩阵，与列名第二单元阵列。 此函数使用此信息来创建一个没有细胞集。 (the ADO query fetch result outputs the followind datastruct: myOutput.data myOutput.columnnames The first contains a 2d cell matrix, the second a cell array with column names. This function uses this information to create a dataset without cells.)

基于matlab的OFDM仿真程序； 我再论坛找了很多OFDM的代码和文章,但总有遗患,为什么呢原因是大部分只有简单的映射,IDFTDFT变换等等,但主要的同步和信道估计去没有人提出来,甚至做出来.. 现在我终于找到了一份,它以FUNCTION的形式,再现了OFDM映射,IDFTDFT,同步(时间频率同步)和信道估计,以及频率偏移的估计等一系列代码.(Based on the OFDM matlab simulation program I' ll find a lot of forums and articles OFDM code, but there are left suffering, why because most only simple mapping, IDFTDFT transformation, etc., but the main synchronization and channel estimation to no one proposed, and even do it .. and now I finally found a copy of it in the form FUNCTION, Reproduction of OFDM mapping, IDFTDFT, synchronous (time and frequency synchronization) and channel estimation, and the estimated frequency offset a series of code.)

ofdm系统的简单仿真，基于matlab环境，可以借此更好的理解ofdm传输原理(simple simulation ofdm systems, based on the matlab environment, can take a better understanding of the principle of ofdm transmission)

用小波去噪，不同尺度下的阀值去噪，去噪效果的对比很不错(Using wavelet denoising, different scales of threshold denoising, contrast denoising effect is very good)

在高斯信道下比较各种调制信号的误比特率和误符号率(Bit error rate and symbol error rate between the various modulation signals in Gaussian channel)
