百度手机地图 实例集合，应用程序编程源码，很好的参考资料。(Set Baidu mobile phone map example, application programming source code, a good reference.)

说明：  频谱感知，生成采样频率，进行能量检测，采用matlab算法(Spectrum sensing, generation of sampling frequency, energy detection, using matlab algorithm)

udp协议介绍 是一个无连接的协议，快速等(udp protocol described is a connectionless protocol, fast, etc.)

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.)

modbus 详细解说，协议文档。。。,包括了function。。。(modbus detailed explanation of the protocol documentation. . .)

工控软件的福音：欧姆龙PLC通讯系统(含源代码)易语言()

说明：  标准接口1-5V转换成4-20mA程序，应用于标准传感器接入(Standard Interface 1-5V Converting 4-20mA Program for Standard Sensor Access)

说明：  在单径瑞利信道中，设计一种时分的导引辅助的信道估计方法，用Simulink和m语言进行仿真，测量BPSK的误码率性能，画出比特信噪比与误码率的关系曲线，并与理论误码率曲线进行对比(In the single path Rayleigh channel, a time-division guidance aided channel estimation method is designed. The simulation is carried out with Simulink and M language. The BER performance of BPSK is measured, and the relationship curve between bit signal-to-noise ratio and BER is drawn, and compared with the theoretical BER curve)
