极化码的matlab实现，包括了完整的编码以及译码程序(polar coding and decoding)

TD-LTE下行传输采用了MIMO-OFDM的物理层构架，通过最多4个发射天线并行传输多个（最多4个）数据流，能够有效地提高峰值传输速率。LTE的物理层处理过程中，预编码是其核心功能模块，物理下行共享信道的几种主要传输模式都是通过预编码实现的。(The td-scdma LTE downlink transmission adopted MIMO - OFDM frame, the physical transmission antennas parallel transmission by up to four more (up to 4) data flow, can effectively improve the peak transmission rate.LTE) in the process of the physical layer of precoding is its core function module, several kinds of main physical downlink Shared channel transmission model is achieved by precoding.)

说明：  实现雷达信号处理仿真，LFMMTIMTD(radar signal processing,including MTI,MTD,LFM signal)

这是一个实现CS的QQ，并带有链接数据库的功能，主要功能有注册，群聊，私聊等(This is a realization of C S of the QQ, and with a link to a database functions, the main function of registration, group chat, private chat, etc.)

步进频率雷达目标的运动参数估计 (Target Motion Parameter Estimation of stepped- frequency radar)

说明：  截获接收机采用时频分析进行跳频通信的参数估计程序(Intercepting the parameter estimation procedure of the receiver for time-frequency analysis for frequency hopping communication)

给出 了 GOLD 码 的 生成 程序以及分析程序，同时 还并 附有详细 注释可以 运行成功(GOLD given code generation procedures and analytical procedures, but also with detailed notes can run successfully)

3gpp关于usim应用测试指导规范，通用的，不光是td scdma(rd Generation Partnership Project Technical Specification Group Core Network and Terminals UICC-terminal interface Universal Subscriber Identity Module (USIM) application test specification (Release 4) )

用 MATLAB 对基带数字通信系统进行仿真。整 个系统模拟了发送和接收的全过程。其中调制部分采用 16QAM，并且采用基带传输(Using MATLAB for baseband digital communication system simulation. The system simulates the entire process of sending and receiving. Where the modulation part is 16QAM, and using the base band transmission)
