fsk modulator/demodulator

这个仿真程序用于实现DS-CDMA通信系统仿真(The simulation program used to implement DS-CDMA Communication System Simulation)

基于matlab平台，用mallat算法对图像进行降噪处理(Based on matlab platform, with mallat algorithm for image noise reduction processing)

通过直方图均衡化使图像灰度均匀分布，使一定范围内象元值的数量大致相等，以此加强细节，提高图像处理的清晰度，便于观察以及计算机进行分析处理(failed to translate)

将整个空间进行划分，变成无数的小空间，其中小空间的长度可变。(The entire space is divided into numerous small space, wherein the variable length of the small space.)

有源低通巴特沃斯滤波器设计根据给定的参数值设计有源滤波器(Active low-pass Butterworth filter design parameters according to the given active filter design)

多约束的广义预测控制算法。使用fmincon求解(GPC with constrains code is proposed. And fmincon function is uesed.)

用matlab编写的关于天线问题的程序，用于计算细直导线电容(Prepared using matlab antenna problems on the procedures used to calculate the straight fine-wire capacitance)

说明：  在Bialas與Karwan的第 解演算法 [13] 則是搜尋限制式解域中的端點，並且歸類為已搜尋端點集合、未搜尋端點集合、可行解端點集合、非可行解端點集合，再從可行解端點集合中找出使高階目標值最佳的端點。(Bialas and Karwan in the first solution algorithm [13] is the search for solutions in the domain of endpoint constraints, and the endpoints are classified as a collection of search, not search a collection of endpoints, the endpoint set of feasible solutions, non-feasible solution side point set, then the endpoint from the set of feasible solutions in order to identify the best target endpoint.)

This program demonstrates OFDM systems using QPSK modulation. OFDM system uses fft/ifft technique to transmit or receive parallel data streams.
