16QAM-OFDM

说明：  polar code for matlab communication

OFDM系统的LS和DFT信道估计的算法分析比较(LS and DFT OFDM system channel estimation algorithm analysis and comparison)

MFC写的2个程序，通过socket通信，上下位机的。上位机发送一个名字给下位机，下位机通过查询数据库取得电话号码传回上位机,带详细文档。(MFC write two procedures, through the socket communication, next-bit machine. PC to send a name to the next crew, the next crew by querying the database to obtain the phone numbers return PC)

this describe the rouring protocol direct diffusion for wireless sensor network

说明：  主要运用matlab仿真mpsk、16qam的星座图，里面有很多关于函数的参数注释，适合初学者(Realization of MPSK 16QAM constellation in MATLAB)

这个程序采用现代谱估计的ARMA参数模型算法对信号的功率谱做了估计(The program uses the ARMA parameter model algorithm of modern spectral estimation to estimate the power spectrum of the signal.)

OFDM(正交频率调制)实现多载波调制基本思想是将带宽信道分解成许多并行的窄子信道，是每个子信道的想干带宽，从而实现平稳衰落。搭建了完整的OFDM信道链路系统，运用三种不同的信道估计方法(LS信道估计、DFT信道估计、Improved-DFT信道估计)，并对AWGN理想信道和衰落信道误码情况进行了仿真和比较。(OFDM (Orthogonal Frequency Modulation) multicarrier modulation basic idea bandwidth channel is decomposed into a number of parallel narrow subchannels, each subchannel wanted bandwidth, in order to achieve a smooth fading. Build a complete OFDM channel link system, the use of three kinds of different channel estimated method (LS channel estimated, to the DFT letter Tao estimates, Improved-the DFT letter Road estimated), and AWGN ideal letter Road and fading channel bit error situation conducted a simulation and comparison .)

有客户端的聊天软件，可实现网络通讯，对于了解网络编程有帮助(A client chat software, network communications, network programming help for understanding)

本人编写的一个根据五行八卦理论用来测试手机号吉凶的小程序,本程序只供大家消遣,且莫过于在意,呵呵()
