Title:
SELECTIVE RADIO CALL RECEIVER
Document Type and Number:
Japanese Patent JP2699956
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent the generation of a call loss and the consumption of battery current due to turning on by a receiving part by preventing the deviation of a frame to a transmission frame.
SOLUTION: After the establishing offrame synchronization, CPU 111 calculates the ideal value of frame information which should be received at the time of next reception in intermittent receiving operation, and at the time of next reception CPU 111 compares frame information actually received after detecting a frame synchronizing signal and the ideal value with each other. When the comparing result is mutually different, CPU sets the ideal value of frame information to a counter 108 and at the same time, CPU considers possibility that the value originally set in the frame counter 108 is wrong and that frame information received this time is correct, to predict frame information at the time of next reception in the intermittently receiving operation in the case of judging correct frame information. When frame information actually received at the time of next reception coincides with the ideal value, CPU sets a value based on the ideal value to the frame counter 108.
