找到的编写的CDMA通信系统的仿真程序，发上来分享一下，同时附带具体的程序说明文档。(Found in the preparation of the CDMA communication system simulation program, a table to share, at the same time attached to the specific procedure documentation.)

一个emd分解程序，包括瞬时频率，瞬时幅值，边际谱，Hilbert谱(A emd decomposition process, including instantaneous frequency, instantaneous amplitude, the marginal spectrum, Hilbert spectrum)

说明：  这是一个用FDTD算法计算二维金属方柱散射场RCS的matlab程序.采用UPML吸收边界条件和高斯脉冲源激励,对于学习FDTD方法中的激励源加入,近-远场外推,吸收边界设置等很有帮助 (This is a two-dimensional metal with the FDTD algorithm to calculate the scattering RCS of a square cylinder matlab program. UPML absorbing boundary conditions and using the Gaussian pulse source excitation, FDTD methods for studying excitation source added, near- far field extrapolation, absorbing boundary settings, and helpful)

a design methodology is introduced that blends the classical PID and the fuzzy controllers in an intelligent way and thus a new intelligent hybrid controller has been achieved. Basically, in this design methodology, the classical PID and fuzzy controller have been combined by a blending mechanism that depends on a certain function of actuating error. Moreover, an intelligent switching scheme is induced on the blending mechanism that makes a decision upon the priority of the two controller parts namely, the classical PID and the fuzzy constituents. The simulations done on various processes using the new hybrid fuzzy PID controller provides ‘better’ system responses in terms of transient and steady-state performances when compared to the pure classical PID or the pure fuzzy controller applications. The controller parameters are all tuned by the aid of genetic search algorithm.

研究用于自适应均衡器的LMS算法的性能，数据源产生有零平均和单位方差的由符号+1和-1组成的Bernoulli的序列{I(n)}.数据源之后的信道可以用升余弦脉冲响应来模拟。 (study for the adaptive equalizer LMS algorithm performance, Data Sources have zero mean and unit variance from the-1 and a symbol of the Bernoulli sequence (I ( n)). Data Source after the channel can be raised-cosine pulse response simulation.)
