wsn的仿真源码,无须帐号,就可下栽.希望对大家有帮助啊-WSN simulation source, do not need an account, you can下栽. I hope all of you help ah

A simple example to verify the feasibility of applying compressed sensing for channel estimation. The pilot applies a PN pattern in the frequency domain. The density of pilot is less than the Nyquist sampling rate. Also it is assumed there are sparsity in the channel taps, which is the basis for applying compressed sensing.

应用背景实现串口通信基类，和扩展类，可以方便的实现串口通信。在基类上扩展了两个应用类，对于两个应用类实现相应通信协议的解析关键技术应用到了串口通信技术，RS232，并且对于实际应用进行了协议解析。通过基类的继承可以实现其它串口通信协议的解析与通信。很好的封装了串口通信应用。利用多线程技术实现了收发数据。

TOP PORT (USB) 调试接口说明 本接口是利用PL-2303HX的USB转RS232的接口芯片设计实现了一个TTL(5V)的RS232串口，并且利用了PL-2303HX的2个GPIO口软件模拟了一个低速的I2C总线.该接口由USB接口提供5V电压，可自带2Kbit(24C02)数据备份EEPROM (单独读写通道,不占用I2C总线地址)。并可对外提供小于250mA的5V电压。尤其适合WIN-XP以后的没有并口和串口笔记本电脑。整机成本不到￥20RMB。 -TOP PORT (USB) interface debugging of this interface is the use of PL-2303HX the USB to RS232 interface chip design to achieve a TTL (5V) of the RS232 serial port, and use of PL-2303HX the two GPIO port software simulation of a low-speed I2C bus. The interface from the USB interface to provide 5V voltage, can bring their own 2Kbit (24C02) data backup EEPROM (separate read and write access, do not occupy I2C bus address). And may provide less than 250mA of 5V voltage. WIN-XP is particularly suitable for subsequent parallel and serial no notebooks. Machine costs less than ￥ 20RMB.
