Apparatus and Method for Minimizing the Turn on Time for a Receiver Operating in a Discontinuous Receive Mode

摘要

An apparatus and a method for minimizing the turn on time for a receiver operating in a discontinuous receive mode. 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 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. The present invention advantageously minimizes the turn on time for the receiver (104) operating in a discontinuous receive mode to save current drain.
