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 .)

说明：  STC单片机多机连级串口程序可实现.416路控制. 串口和485都可以使用、 一个程序可以用在26块控制板上，通过拔码开关给板子编号，每块板可以过滤分析所接收到不同的代码。进行继电器的动作，能返回数据，因使用定时器发送返回，不会阻塞或者代码错乱、可以 用在中控，物联网，等各种控制场合。修改代码后，能达到上千路的控制。(STC single-chip microcomputer multi-level serial port program can realize 416 channel control. Serial port and 485 can be used. One program can be used on 26 control boards. Each board can filter and analyze different codes received by numbering the boards with the pull-out switch. Relay operation can return data, because the timer is used to send the return, it will not block or code confusion, and can be used in central control, Internet of things, and other control occasions. After modifying the code, it can achieve thousands of control.)
