中文说明：该代码按照zigbee物理层协议栈，经过整形滤波，上下采样，应用巴克码达到易于在解调时寻找同步点的目的，在用matlab仿真时，为了模仿真实信道，在代码中加入与实际噪声最接近的高斯白噪声，进行OQPSK调制解调，最终在一定的信噪比下，实现解调完全正确
English Description：
The code in accordance with the ZigBee physical layer protocol stack, after shaping filter, sampling, applying Barker codes achieve the easy to find synchronization points in demodulation, using MATLAB simulation, in order to mimic the real channel, in the code added and closest to the actual noise of Gaussian white noise, OQPSK modulation and demodulation, eventually in a certain signal to noise ratio to achieve completely correct demodulation
