Patent ID: 7539518

Claim:
A time division multiplexed signal receiver apparatus in which an operation of a receiver circuit is started before reception of an assigned signal, and stopped, when the reception of the assigned signal ends, until before reception of a next assigned signal, comprising: a pull-in time measuring unit operable to measure a pull-in time necessary for the operation of the receiver circuit to stabilize from when the operation of the receiver circuit is started; a holding unit operable to hold information showing at least one pull-in time previously measured by the pull-in time measuring unit; an evaluation unit is operable to evaluate a quality of the received assigned signal, based on the information held in the holding unit; a determination unit operable to determine an operation start time at which the operation of the receiver circuit is to be started for the reception of the next assigned signal, based on a result of the evaluation by the evaluation unit; and a control unit operable to start the operation of the receiver circuit at the determined operation start time.
