盲多用户检测的LMS和RLS算法,在DS/CDMA通信系统中，为了解调出用户的有用信息，必须尽可能地抑制由其它用户扩频信号产生的多址干扰（MAI，Multiple Access Interference）。尽管最佳多用户检测器可以很好地抑制MAI，但其运算量会随着用户数的增加而呈指数增加。盲多用户检测技术可以在不知道其他用户信息的情况下检测出目标用户，所以在实际应用中有着十分重要的应用前景.(LMS and RLS algorithm Blind Multiuser Detection in DS/CDMA communication system, in order to demodulate the user useful information, must be possible to inhibit the spread spectrum signals generated by other users multiple access interference (MAI Multiple Access Interference) . Although the optimal multi-user detector can suppress MAI, but its computational complexity increases exponentially with the number of users increase. Blind Multiuser Detection technology can not know the other user information detected the target user, has a very important application prospect in practical applications.)

可以计算两端固定的平面梁的挠度，当划分的单元越多时，梁的挠度值逐渐趋于稳定 (Can calculate the plane beam fixed at both ends of the deflection, when the division of the more units for some time, beam deflection gradually stabilized)

异步电机abo仿真模型基于matlab的simulink仿真 源码(Abo simulation model of induction motor based on the simulink simulation matlab source)

说明：  描述了matlab的程序设计语言的编写、实例、有利于初学者使用。(Describes the matlab programming language, for example, writing for beginners.)

说明：  针对多通道卷积混叠模型,基于信息理论的最小熵准则,利用单时间点观测样本给出了一类多通道盲反卷积 方法,这种方法不同于其它方法的地方在于考虑了源和观测信号的上下文信息.(A blind deconvolution algorithmfor a multi- channel convolution mixing model was derived. The algorithm is based on a minimum entropy contrast of information theory. The difference of the algorithm with the others is that the context message is used in contrast.)

码分多址，是在无线通讯上使用的技术，CDMA 允许所有的使用者同时使用全部频带(1.2288Mhz)的系统仿真(CDMA is used in wireless communications technology, CDMA allows all users to simultaneously use all bands (1.2288Mhz) System Simulation)

解优化问题的单纯形法，用矩阵形式推导完成，后附变量解释和大体流程解释。(Simplex method to solve optimization problems, reducted from matrix, following is variable explaination and general process explaination.)

说明：  首先，在非视距环境中，信号传播将产生多径效应，这将导致对到达时间的错误估计。其次PSO(Firstly, in NLOS environment, signal propagation will produce multipath effect, which will lead to wrong estimation of arrival time. Second, PSO)
