Appl. No.:

10/011603

Inventors:

Brian H. Bremer - Arlington Heights IL, US
Jeremy A. Jacobson - Bothell WA, US
Lawrence R. Schumacher - Hoffman Estates IL, US

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

G08C017/00

US Classification:

Abstract:

A method for reducing current drain in a communication device includes a step of determining when the communication device is transmitting. A next step includes lowering the current level to the receiver when communication device is not transmitting. A next step includes raising the current level to the receiver when communication device is transmitting. Changing the current level alters the linearity of the receiver. As a result, the communication device reduces power consumption while operating in a traffic channel. The system is applicable to full duplex systems such as code division multiple access (CDMA) systems.

Abstract:

A first sequence state storage module () periodically stores a present state () of a long code generator (). Following a restoration of power after a power cut condition, or following the termination of any other interruption of the generation of the long code, a sequence recovery module () then provides an updated present state (). The updated present state () is based upon a stored present state () and a time value () that is reset whenever the present state () of the long code or other sequence is stored and that is available even when the long code or other sequence is interrupted.
