costas环解调

说明：  TCPIP在51单片机中的使用，一看就会，非常简单可靠实用(TCPIP )

说明：  完整的手机主题网站,功能完善,并且有大量资源(Complete cell phone theme of site, function perfect, and there is a lot of resources)

RTD2660源码，可以作为参考或者开发之用。(The source of RTD2660.)

信息经格雷码映射，进行QPSK调制并通过AWGN信道发射，在接收端进行QPSK解调，并统计误符号率和误码率。(Information on the Gray code mapping, QPSK modulation and emission through the AWGN channel, QPSK demodulator at the receiving end, and the statistical symbol error rate and bit error rate.)

说明：  使用wifi信号进行人体定位追踪，里面有AOA和TOF的计算能够准确计算人体位置(Using WiFi signal to locate and track human body.The calculation with AOA and TOF can accurately calculate the position of human body)

串口程序，用于通过串口控制空调，可以在这个程序基础上修改其他代码(used for serial port)
