单片机发送报文控制手机模块GR47进行gprs连接登陆，发送接收数据(SCM reportedly sent mobile phone text control module for EDGE connectivity GR47 landing, send and receive data)

matlab中离散信号小数点时延的实现算法,可以精确实现一段序列的延时(numerical time-delay)

HLP A+ Modbus 标准通讯协议格式，上位机发送数据格式，正确时变频器返回数据格式(This bit will be set to logic 1 when the receive buffer has been read and contains no new information. If there is new information available in the receive buffer that has not been read, this bit will return to logic 0. RXBMT = 1 when in Master Mode.)

说明：  对信道进行LS信道估计，并使用Decision-Directed的方式进行降噪。(Channel Estimation Decision Directed)

说明：  基于modbus rtu封装的通讯协议，很好用(Communication protocol based on Modbus RTU encapsulation)
