当前经典的合成孔径雷达成像算法为：RD，CS和RMA。压缩包里有这三个算法的Matlab代码，这些代码对初学者是非常有用的。 (Three classic image formation algorithm for Synthetic Aperture Radar(SAR) are RD, CS, RMA. They can be obtain in Matlab Code, and they may be usefull to beginners. )

说明：  混沌工具箱，用matlab编写的，该工具箱包括了混沌时间序列分析与预测的常用方法(Chaos toolbox matlab prepared to use the toolbox, including a chaotic time series analysis and forecast of the common methods)

Block-interleaver/deinterleaver according to the IEEE 802.11-2007 Defined by two step-permutation : The first permutation ensures that adjacent coded bits are mapped onto nonadjacent sub-carriers. The second ensures that adjacent coded bits are mapped alternately onto less and more significant bits of the constellation and, thereby, long runs of low reliability (LSB) bits are avoided. Tested and works well

本书详细介绍了如何利用matlab进行算法运行时间的分析和比较，并附很多例子，简单易懂。(This E-book covers mainly about how to use matlab to analyse the algorithm running time, and easy to understand)

对电网不平衡情况下的三相PWM整流器进行了详细的建模分析，并在此基础上研究了两种不平衡控制策略。其一是抑制网侧负序电流的控制策略，主要控制三相PWM整流器交流电流对称正弦化控制。其二是抑制直流电压谐波分量的控制策略，主要控制三相PWM整流器从电网吸收平衡的瞬时功率，消除直流电压中的各次谐波分量。(Research on the Control strategy of Three-Phase PWM Rectifiers under Unbalaneed Grid Voltage)
