说明：  该程序给出了利用Saleh模型进行功率放大器预失真的过程．(The program gives the power amplifier pre-distortion with Saleh models.)

multipath signal description with read technique

将压缩感知应用于基于训练序列的信道估计中，代码展示了压缩和估计过程。(Will be used in compressed sensing training sequence based channel estimation, the code shows the compression and estimation process.)

CS-MIMO雷达参数估计，这个主要是单基地MIMO雷达的例子(CS-MIMO radar parameter estimation, this is a major example of monostatic MIMO radar)

说明：  OFDM系统仿真 ----比较OFDM系统的IDFT/DFT实现与模拟调制实现仿真代码，其中假设OFDM系统包含8个子载波，fc=1 Hz，子载波频率间隔为1 Hz，每个子载波采用4-QAM调制，符号周期为1秒(OFDM IDFT/DFT 4-QAM FFT/IFFT)

说明：  turbo码的c语言程序，使用c语言来完成整个turbo码的编解码过程，并且程序后附带比较详细的解释(turbo code c language program, use c language to complete the entire turbo code codec process and procedures attached to explain it in more detail)

说明：  近两天由于研发需要OPNET这个仿真软件，同时要求可以支持wimax仿真模型，对该仿真软件的研究还需要继续进行 好不容易在网络上找到了最新版的OPNET 14.5的软件，但是安装的确出现了很大的麻烦，最后通过查阅网络上对之前版本安装的经验解决了安装过程中的问题，因此将这些分享给大家： (Almost two days because of this R &amp D needs OPNET simulation software, also required to support wimax simulation model, the simulation software is also the need to continue the network finally found the latest version of the OPNET 14.5 software, but certainly there was an installation much trouble, and finally access to the network through the installation of the experience of the previous version to solve the problems during the installation process, it will share all of these:)

说明：  MIMO-OFDM系统仿真，MIMO-OFDM系统不同信道估计的对比，模型框架的搭建(MIMO-OFDM (Simulink and Matlab))

手机RSS阅读器(html5)，应用程序编程源码，很好的参考资料。(Mobile phone RSS reader (HTML5), application programming source code, a good reference.)

这个程序除了接收机同步、信道编码没有加入外，基本上反映了一个OFDM系统的特性： 1. qpsk/16qam/64qam映射、解映射 2. OFDM调制解调（循环前缀，FFT等） 3. 非整数采样时刻多径时延的多径信道 4. Rayleigh或者Rician多径信道 5. 信道的连续时变（非block fading） 6. 线性插值信道估计 7. FFT变换域插值信道估计(In addition to this program receiver synchronization, channel coding have not joined, the basically reflect the characteristics of an OFDM system: 1. Qpsk/16qam/64qam mapping, mapping solution 2. OFDM modulation and demodulation (cyclic prefix, FFT, etc.) 3. Non- integer sampling instant multi-path delay of multi-path channel 4. Rayleigh or Rician multipath channel 5. a continuous time-varying channel (non-block fading) 6. linear interpolation channel estimation 7. FFT transform domain interpolation channel estimation)
