中文说明：用matlab仿真了IEEE802.15.4在2.4Ghz频段OQPSK PHY的收发过程，文件包含主文件main.m及其模块函数，实现了IEEE802.15.4 OQPSK PHY从PSDU到PPDU帧组装，比特到符号映射，符号到32位码片映射，以及OQPSK调制，接受实现了匹配接收，能够正确解调得到发送消息
English Description：
MATLAB simulation in 2.4Ghz band IEEE802.15.4 OQPSK PHY transceiver, the file includes the master file main.m and the module functions, implements IEEE802.15.4 OQPSK from PSDU PHY to the PPDU frame Assembly, bit into the symbol mapping symbols to a 32-bit chip mapping and OQPSK modulation, accept to achieve a matching receive to properly demodulation to be sending a message
