Embodiment Construction

[0032] Please refer to FIG. 1 , which is a functional block diagram of a wireless communication device 100 . For simplicity, FIG. 1 only shows the input device 102 , output device 104 , control circuit 106 , CPU 108 , storage device 110 , program code 112 and transceiver 114 of the wireless communication device 100 . In the wireless communication device, the control circuit 106 executes the program code 112 stored in the storage device 110 through the central processing unit 108, thereby controlling the operation of the wireless communication device 100, and can receive the signal input by the user through the input device 102 (such as a keyboard), Or output signals such as picture and sound through the output device 104 (such as a screen, a speaker, etc.). The transceiver 114 is used to receive or send wireless signals, transmit the received signals to the control circuit 106 , or output the signals generated by the control circuit 106 by radio. In other words, in terms of t...
