MOBILE TERMINAL EQUIPMENT |
摘要 |
PROBLEM TO BE SOLVED: To extend the service time by reducing power of the mobile communication terminal equipment in an intermittent reception. SOLUTION: The mobile communication terminal equipment adopting the CDMA system is provided with a SAW matched filter 31 that conducts partial correlation arithmetic operation with a pilot PN code at an intermediate frequency band and outputs an initializing pulse in matching with production of a correlation peak for a pause period at intermittent reception, and a PN timing generating circuit 51d is initialized by the initializing pulse to store pilot PN synchronization. As a result, power supply of a base band front end section 4 is interrupted, the operation of a rake engine section 5 is stopped to reduce the current consumption for a pause period. |
