Abstract
The invention concerns a mobile communication terminal for use in mobile communication or mobile satellite communication. In the mobile communication terminal provided with a DSP for processing a communication signal according to the mode of communication, a CPU for indicating the communication mode to the DSP, and a clock generator for supplying a clock signal to the DSP, the clock generator changes the clock signal for the DSP in response to a request for changing the frequency from the DSP based on the communication mode.
Claims10
A mobile communication terminal having more than two communication modes, comprising:
- a CPU for selecting a communication mode from said more than two communication modes and supplying a frame signal for signal processing;
- a DSP for processing a communication signal on a framewise basis in accordance with said selected communication mode;
- and
- a clock generator for supplying to said DSP a clock signal, a frequency of said clock signal being determined in accordance with said selected communication mode and changed on a basis of a timing of said frame signal.
A mobile communication terminal having more than two communication modes, comprising:
- a CPU for selecting a communication mode from said more than two communication modes and supplying a frame signal for signal processing;
- a DSP for processing a communication signal on a framewise basis in accordance with said selected communication mode;
- and
- a clock generator for supplying to said DSP a clock signal, a frequency of said clock signal being predetermined;
- wherein said DSP includes a phase locked loop for frequency dividing said clock signal and a frequency dividing number set in said phase locked loop is changed on a basis of a timing of said frame signal, to a number determined in accordance with said selected communication mode.
