Title:
無線通信端末
Document Type and Number:
Japanese Patent JP4601862
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a wireless communication terminal that can accurately receive synchronizing data without increasing the power consumption in a standby so as to enhance the synchronism holding and the power consumption even in the case of using a clock oscillator with low precision. SOLUTION: A temperature detector 63 detects the ambient temperature of a low speed clock oscillator 62 synchronously with a received start timing of each period, and a temperature information management section 65 calculates the temperature difference between the received start timings of each period on the basis of temperature detection data TM by a temperature detector 63. Then a timing error adjustment section 54 calculates timing error information TG adjusted by reflecting an error component by the calculated temperature difference and a received timing generating section 21 respectively decides a received start timing and a received period for a succeeding period on the basis of the timing error information TG to allow a wireless section 1 to conduct intermittent reception according to the timing information.
