APPARATUS AND METHOD FOR MINIMIZING THE TURN ON TIME FOR A RECEIVER OPERATING IN A DISCONTINUOUS RECEIVE MODE

摘要

The present invention is directed to an apparatus and method for minimizing the turn-on time of a receiver 104 operating in a discontinuous reception mode. In the communication unit 100, the receiver 104 receives a signal 118 having desired data (word A) and unwanted data (word B). Receiver 104 has a discontinuous receive mode of operation that is turned on when desired data (word A) is expected and turned off when unwanted data (word B) is expected. The period during which receiver 104 is turned off is determined. The receiver 104 is turned on at the time before the arrival of the desired data (word A) in response to the period in which the receiver 104 is turned off. The present invention advantageously minimizes the turn-on time of the receiver 104 operating in the discontinuous reception mode to save the current drain.
