MAPBCJR

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:)

MPSK QAM MASK MPSK信号载频估计matlab程序(matlab program of estimating Carrier Frequency of MPSK QAM MASK MPSK signal )

TCM with BCJR (Log-Map) & channel Encoder Coded_Modulation

说明：  构建了基于压缩感知的信号处理系统，并用BPDN算法将频域稀疏信号恢复出来，BPDN算法与GPSR算法类似，属于基追踪算法，复杂度较高但较为精准。(A signal processing system based on compressed sensing is constructed, and bpdn algorithm is used to recover the sparse signal in frequency domain. Bpdn algorithm is similar to GPSR algorithm, which belongs to base pursuit algorithm, with higher complexity but more accurate.)

说明：  基于宏小区及微小区MIMO信道模型，比较了MIMO信道在两种传输环境中的空间相关特性，通过数值分 析方法得到了两类信道空间相关性随发送端、接收端天线阵列的分布而变化的特征曲线，并分析比较了信道参数， 即到达角的角度扩展，对空间相关性的影响。(The space correlation is analyzed in different propagation conditions including the MIMO macro-cell and micro-cell applications. The characteristics curves describing the space correlation versus the distance of antennas are obtained according to the numerical analysis. The effect of the spread of the angle of arrival on the space correlation is also investigated. )

说明：  实现了8PSK的调制，画出了时域及频域信号波形，以及8PSK的星座图。(The 8PSK modulation is realized, and the time domain and frequency domain signal waveforms, as well as the 8PSK constellation diagram are drawn.)

说明：  LTE ofdm编码调制解调仿真，平台为matlab(Simulation of OFDM coded modulation and demodulation)

vc++开发的socket通信类（含客户端和服务端）(socket communication(include client and server))

说明：  PDA开发 WINDOWS 平台上的PDA开发(PDA development on WINDOWS platform PDA development)
