Adaptive antenna system signal detection

摘要

A system and method for processing signals in a communication system is disclosed herein. The system and method comprises processing steps and processing logic for generating a downlink subframe comprising a preamble and a plurality of data bursts within a predetermined frequency band; embedding first and second sets of downlink subframe parameters in the downlink subframe; transmitting the downlink subframe; receiving the downlink subframe; processing data in the preamble to obtain channel quality indicator (CQI) information; and using the CQI information to select either the first set or set second set of downlink subframe parameters to process the data bursts in the downlink subframe.

1. A method of processing signals in a communication system, comprising:
receiving a downlink subframe within a predetermined frequency band, wherein the downlink subframe is one of two or more downlink subframes comprised in a downlink frame; decoding one or more portions of the downlink subframe; determining a relative channel quality responsive to decoding the one or more portions of the downlink subframe; when the relative channel quality meets a threshold criterion:
searching all scannable frequencies within said frequency band for adaptive antenna system (AAS) parameters; andsubsequently searching all scannable frequencies in said frequency band for channel parameters when no AAS parameters are detected; and decoding a data burst in accordance with the AAS parameters or channel parameters.
