qpsk调制在awgn/rayleigh信道下的误码性能比较，以及信号的功率谱和星座图-QPSK modulation in awgn/Rayleigh Channel Performance Comparison of error, and the signal power spectrum and constellation

 该程序是使用Matlab仿真协同通信的DF（解码转发）基本性能，基本模型S-R-D三个节点，接收端使用MRC（最大比合并）。固定DF由于SR信道的错误，其性能受到限制，在大SNR情况下不能获得有效分集。而当SR距离足够近的时候，可能获得一定的分集增益。     该程序也可以作为学习Matlab 通信仿真的入门实例

This function generates normalized rayleigh samples based on Inverse DFT

环境监测无线传感器网络节点的设计 针对环境监测的要求,开发了一种兼容型的无线传感器网络节点系统。该系统以MSP430FG4618为核心,采用 CC2420 214G射频芯片,软件上移植了德州仪器( TI) ZigBee协议栈,并在应用层开发了通信程序。该系统可以组建成稳定的网状网络,功耗低,数据传输稳定.-Environmental monitoring wireless sensor network node designed for environmental monitoring requirements, to develop a compatible system for wireless sensor network node. The system MSP430FG4618 as the core, using radio frequency chip CC2420 214G, software transplanted Texas Instruments (TI) ZigBee protocol stack, and the application layer has developed a communication program. The system can be formed into a stable mesh networking, low power consumption, data transmission and stability.
