微机之间串口通信,实现两台微型计算机之间快速简便的串行通信,()

说明：  polar 代码，使用matlab进行仿真，实现了polar代码基本功能，并提供polar基本原理说明(matlab polar simulation)

this is for calculate qam and it is very good to practice so good u can play

描述了混沌的序列的优选，如何利用均方根值进行优选。(Describes the preferred sequence of chaos, how to make use of root-mean-square value optimization.)

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 .)

默认产生（0，1）的高斯随机数，参数可调(Gauss random number (0,1) is generated by default with adjustable parameters.)

OFDM仿真，包括仿真图，功率谱，星座图等(OFDM simulation, including simulation diagram, power spectrum, constellation diagram, etc.)
