GSM通信协议这个事是开源设备，请大家都来参与和讨论-This is GSM.

根据GSM协议，实现8PSK调制。其中OPSK是主函数-According to the GSM protocol, to achieve 8PSK modulation. Which is the main function OPSK

根据GSM协议，利用查表法的方法实现8PSK，教标准方法，运行效率更高，lt8psk是主函数-According to the GSM protocol, using look-up table method to achieve 8PSK, teach standard methods, greater operating efficiency, lt8psk is the main function
