Title: Radio communication equipment
Inventor: SAKAI HIROSHI
IPC: H04W88/06
Filed: 1998-11-27
Abstract: PROBLEM TO BE SOLVED: To provide a radio communication equipment which can suppress power consumption when DSP(digital signal processor) executes a sound encoding/decoding processing. SOLUTION: 25 MHz and 16 MHz are set in DSP 12 for sound processing as operation frequencies. When a control part 2 detects an originating call or an incoming call, it identifies whether a communication line on the originating call or the incoming call is a PDC line or a PHS line and selects 25 MHz or 16 MHz in accordance with the identified result and causes DSP 12 to execute a sound encoding/decoding processing with the selected operation frequency. Thus, DSP 12 for sound processing is prevented from operating by the operation frequency higher than required and therefore power consumption can be suppressed.
