N-Rcalculation

MC-CDMA Walsh code for the communication systems.

DPD设计的硕士论文，相当的不错！值得收藏！(DPD design master thesis, is pretty good! Worth collecting!)

提供了集中语音去噪的matlab代码，并提供了相应的声音文件(Provides a centralized voice denoising matlab code, and provide the corresponding sound files)

cmos晶体管的matlab仿真和模拟，可以实现cmos晶体管的电压电流传输特性的模拟。(cmos transistors in Matlab simulation and modeling, cmos transistors can achieve the voltage and current characteristics of the transmission simulation.)

基于二阶统计量与四阶通计量的时延估计算法。(Delay estimation algorithm with second-order and fourth-order statistics.)

a simple source code to practice the ODE45 (Rung kutta) integration methode

码分多址(CDMA)技术作为第三代移动通信系统的核心技术，具有容量大、抗干扰能力强等优点。然而,传统的CDMA系统属于窄带扩频系统,它的数据速率比较低,不能胜任新一代移动通信系统 （beyond 3G）高速数据通信的需要。而多载波传输技术－正交频分复用（OFDM），作为后三代移动通信的核心技术，则具有高数据速率传输的特点。(Code Division Multiple Access (CDMA) technology as the third generation mobile communication system' s core technology, high capacity, anti-interference ability and so on. However, the traditional narrow-band CDMA system is spread spectrum system, and its relatively low data rate, can not do next-generation mobile communication systems (beyond 3G) high speed data communication needs. The multi-carrier transmission technology- orthogonal frequency division multiplexing (OFDM), after three generations of mobile communications as a core technology, the high data rate transmission characteristics.)

说明：  m序列的产生方法的源代码 matlab仿真 希望初学者有用(m sequence generator method )

可以提取叶脉，用matlab写的。用的是rgb2yuv，然后用hough变换(it can extract vein matlab rgb2yuv and hough translation)
