matlab图像集合变化与图像增强操作以及报告 (MATLAB image collections and image enhancement operations and reporting)

动态PCA方法，引入动态时间l，考虑变量本身的时序自相关性，同时还分析变量之间的时序相关性,把PCA方法应用到动态数据矩阵。 (Dynamic PCA method, introducing dynamic time l, consider the timing of the variable itself autocorrelation, also analyzed the correlation between the timing variables, the PCA method is applied to dynamic data matrix.)

CDMA 语音编码，在MATLAB环境下可直接运行(CDMA speech coding)

协作频谱感知虽然可提高系统的感知性能， 但随着感知节点数目的增加， 系统资源的占用越来越多， 系统传输效率下降． 分析了协作频谱感知方法的感知性能， 得到协作频谱感知的感知性能与感知节点数目和接 收信噪比之间的关系， 提出了一种新的次级用户节点的选择方法， 该方法有效保证了所选择节点的感知性能， 仿真验证了该算法的有效性和可靠性．(Although the cooperative spectrum sensing can improve the perceived performance of the system, but with the perception of the number of nodes increases, more and more system resources, the system transmission efficiency decreased. Cooperative spectrum sensing method of analysis of the perceived performance of collaborative spectrum sensing by the perception of performance and perception of the number of nodes and the relationship between the received SNR, a new secondary user node selection method, which effectively guarantee perceived performance of the selected node, the simulation proves the validity and reliability.)

常见的buffer设计，包括：Fast ring buffer, Loop buffer, Bip buffer， circular character buffer，可以方便的集成到相关代码中(common buffer example and code, including fast ring buffer, loop buffer, bip buffer, circular character buffer, and they can integrate to relative code easily.)

这是一个针对采用三相三线制有源电力滤波器的matlab仿真model，采用一种带积分的位置跟踪滑模控制方法，实现电源电流的追踪控制。(This is a simulation model for the three-phase three-wire active power filter matlab, using a position tracking with integral sliding mode control method to achieve supply current tracking control.)
