基于natlab的遗传算法的源代码，可以用于遗传算法的优化仿真分析，在解决优化计算问题的时候非常重要。(a program of matlab for GA)

在一个OFDM系统中,一大批正交、重叠,狭窄的subcarriers衰落、传递并联,除可用的传输带宽。分离的理论,subcarriers最小，这是一个非常紧凑的频谱利用率。OFDM主要是由于该系统如何处理多路径干扰在接收机。多路径生成 (In an OFDM scheme, a large number of orthogonal, overlapping, narrow band sub-channels or subcarriers, transmitted in parallel, divide the available transmission bandwidth. The separation of the subcarriers is theoretically minimal such that there is a very compact spectral utilization. The attraction of OFDM is mainly due to how the system handles the multipath interference at the receiver. Multipath generates)

主分量分析是一种基本的多维数据描述方法，是一种能使多维数据按照实际研究的需要更好地描述出来的变换方法。(Principal component analysis is a basic description of the method of multidimensional data is a multidimensional data in accordance with the needs of the actual research to better describe the transformation method can make.)
