WCDMA downlink imulaation using script1.m file. It is good for understanding of 3G networks, specially for wideband coded multiple access in downlink communication!

该算法是lte中信道编码（turbo）的仿真源代码(The algorithm for channel coding is lte (turbo) of the simulation source code)

灰色模型在matlab中的一个程序代码，可用于预测(Gray model in matlab code can be used to predict)

本程序用来提取基音频率，所用的方法为自相关和平均幅度差相结合的方法(This procedure is used to extract the pitch frequency, using a method for auto-correlation and average amplitude difference method of combining the)

Splash Window. A windows program demo.

此代码主要是用于在MATLAB中的图像叠加，现实中主要应用与全景图片。(this code is used mainly in MATLAB superimposed images of the reality that the main application and panoramic images.)

龚纯精通matlab最优化计算。无约束优化问题源程序(restraint optimize)

多径效应的时域表示实际上就是不同路径来的信号存在随机的时延差。对于抗其它扩频信号干扰性能，及抗多址干扰性能。我们这里考虑简单的情况，只考虑一个用户干扰的情况，说明其具有抗多址干扰性能就行。(Multipath effect is actually a time domain representation of the signal path to the existence of different random time delay difference. Other spread spectrum signal for the anti-interference performance, and anti-MAI performance. Here we consider the simplest case, considering only one user interference, indicating its performance with anti-multiple access interference on the line.)
