matlab 系统设计与分析，这本书pdf格式，希望用MATLAB的朋友下载，相信会有很大收获的。(matlab system design and analysis, this book pdf format, wish to use MATLAB' s friends to download, I believe there will be a great harvest.)

说明：  OFDM是将高速串行数据分成成百上千路并行数据,并分别对不同的载频进行调制,这种并行传输体制大大扩展了符号的脉冲宽度,提高了抗多径衰落的性能。同时,在传统的频分复用方法中,各子载波之间的频谱互不重叠,频谱利用率较低。而采用OFDM技术,一个OFDM符号之内包括多个经过调制的子载波的合成信号,每个子载波在频谱上相互重叠,这些频谱在整个符号周期内满足正交性,因而在接受端可以保证无失真恢复,从而大大提高频谱利用率。(OFDM divides high-speed serial data into hundreds of parallel data channels and modulates different carrier frequency separately. This parallel transmission system greatly expands the pulse width of symbols and improves the performance of anti-multipath fading. At the same time, in the traditional method of Frequency Division multiplexing, the spectrum between the sub-carriers does not overlap each other, the spectrum utilization ratio is low. In the case of OFDM, an OFDM symbol consists of multiple modulated sub-carriers, each of which overlaps in the spectrum, which is orthogonal throughout the symbol period, thus, no distortion recovery can be ensured at the receiving end, thus greatly improving the spectrum utilization ratio.)

通信信号中编解码技术的研究，通过生成OFDM信号，经过快速傅里叶变换与反变换，最后用16QAM解调，计算信噪比。(Communication signal encoding and decoding techniques, but by generating OFDM signals, through the fast Fourier transform and inverse transform, and finally with 16QAM demodulation, signal to noise ratio calculation.)

使用MATLAB自带的函数，实现了50Hz带阻滤波器，其中的参数可以修改，即可以实现任意频率的陷波器。(Achieved a 50Hz notch filter)

独立分量分析法工具箱，MATLAB语言，其中包括许多例子.(Independent component analysis toolbox, MATLAB language, including many examples.)

This toolbox implements the same methods on small dadta sets and imlements a trimming method using a random uniform distribution to quickly process large data sets.

说明：  用matlab建立模型设计fpga，文章采用系统模型(Using matlab to establish model design fpga, articles used system model)

用FISHER算法和基于核的FISHER算法实现样品的分类(Algorithm of FISHER FISHER algorithm based on the core sample classification )
