说明：  OFDM系统仿真内容，比较简单的说明，希望有用哦。(OFDM Channel estimation)

华为GTM900AT命令手册，对开发GPRS具有指导意义(Huawei GTM900 AT command manual，It has a guiding significance to develop GPRS )

利用DML算法和SML算法实现到达方位角的估计(Estimation of arrival azimuth using DML algorithm and SML algorithm)

基于libmodbus编译，使用vs2013编译完整，亲测可行。(Compiled based on libmodbus, compiled using vs2013, complete, pro test feasible.)

基于DFT的OFDM信道估计，介绍了三种低复杂度的信道估计器，对于OFDM的信道估计研究很有参考价值(Analysis of DFT-Based Channel Estimators for OFDM)

其中包含了OFDM系统的简单仿真，有SLM算法输入输出的比较，PAPR明显降低(Which contains a simple simulation of the OFDM system, the comparison of the input and output of SLM algorithm, PAPR is significantly reduced)

BPSK调制，采用（15,11）汉明码对信号编码；然后对信号加噪，解调，译码。(BPSK modulation (15,11) Hamming code signal encoding then added noise to the signal, demodulation, decoding.)

说明：  MFC编程 实现数据绘制成曲线。经兄弟推荐最终决定用两个控件MCSCOMM与TeeChart来完成此任务。MCSCOMM控件时vc自带的串口控件，TeeChart Pro是一个强大的VCL图表组件，支持上百种2D和3D图表风格，并提供40多个数学和统计函数、无限制的轴和22个调色板(MFC programming realizes data plotting into curves. After recommendation by brothers, we finally decided to use two controls, MCSCOMM and TeeChart, to accomplish this task. TeeChart Pro is a powerful VCL graphics component that supports hundreds of 2D and 3D graphics styles and provides more than 40 mathematical and statistical functions, unlimited axes and 22 palettes.)

说明：  实现雷达的信息接收的插件脚本，剩下的就是凑字数了，第一次上传东西，不知道有没有人看！(Achieve radar information receiving plug-in script, the rest is the word count, the first time to upload things, do not know if there is anyone to see!)

SeaSon from DB-LAB of HIT 介绍的方法是以在cygwin中安装gdb为例说明。(SeaSon from DB-LAB of HIT is based on the method described to install gdb on cygwin an example.)
