Apparatus and method for minimizing the turnon time for a receiver operating in a discontinuous receive mode

摘要

In a communication unit the receiver receives a signal (118) having desirable data (word A) and undesirable data (word B). The receiver (104) has a discontinuous receive mode of operation wherein the receiver (104) is turned on when expecting the desirable data (word A) and turned off when expecting the undesirable data (word B). A duration of time that the receiver (104) has been turned off is determined. The receiver (104) is turned on at a time prior to the arrival of the desirable data (word A) responsive to the duration of time that the receiver (104) has been turned off. Thus the turn on time more closely approaches the time taken by the receiver to stabilize, resulting in power saving.
