可以产出LDPC_802.16e码字，不同码长不同码率(creat LDPC_802.16e ldpc code)

配置STM32串口并接收和播发数据，需自己注意STM32的引脚连接(Configuring STM32 serial port and receiving and transmitting data)

模拟移动公司的能力平台的rest接口，接口地址除IP和端口外，其它完全一致(Analog Mobile Corporation capabilities platform rest interface, interface address except IP and port, and other completely identical)

Analysis and Simulation Model of Physical Carrier Sensing in IEEE 802.11 Mesh Networks

雷达系统，雷达信号中频非相参积累的简单代码(Radar system, radar signal, intermediate frequency, non coherent accumulation, simple code.)

整个OFDM的matlab仿真代码，使用16qam调制，还有word的文档，讲解很细(The OFDM matlab simulation code, the use of 16 qam modulation, and word document, very fine )

说明：  此文档中主要说明了基于Matlab的时间抽取基2FFT算法的一些注意事项以及程序是可行的。(In this document mainly describes the time taken based on the Matlab-based algorithm 2FFT some attention as well as the procedure is feasible.)

说明：  高阶累积量进行识别常用的数字调制信号，低信噪比下识别率高达90%(It uses the method of high cumulant to recognize usual digital signals, under low SNR, the radio is still over 90%.)

QPSK的编译 设定噪声为高斯白噪声，对2ASK、2FSK、2PSK、2DPSK等各种调制方式及相应的主要解调方式下（分相干与非相干）的误码率进行统计，并与理论值进行比较，以图形方式表示误码率与信噪比间的关系。(QPSK compiled Set the noise is Gaussian white noise, right 2ASK, 2FSK, 2PSK, 2DPSK variety of modulation and demodulation mode corresponding to the main (sub-coherent and non-coherent) error rate statistics, and with the theoretical value comparison, a graphical representation of bit error rate and SNR relationships.)
