Adaptive wireless communication receiver

摘要

The present invention provides a method and apparatus for adaptive processing in a communication system receiver. The adaptive processing facilitates power savings and permits enhanced performance when necessary. This extends a receiver's operation time in receivers that operate on batteries, such as in cordless telephones or cellular telephones. A receiver adopting the principles of the present invention evaluates the characteristics and dynamics of an incoming signal, and based on the quality of the incoming signal, adjusts various aspects of the receiver such as the on-line correlators and analog to digital converters, the timing circuits, the despread equalizers, and the combiner. If the receiver comprises a receiver operation in accordance with the GSM, the receiver may cycle the MLSE detection algorithms or cross correlation may be done over fewer data symbols.
