1. A receiver for signal processing in a mobile station, comprising:
- a front-end processor for receiving a signal;
a searcher coupled to the front-end processor for detecting one or more signal paths in the signal;
a selection module for selecting at least one of the one or more signal paths and selecting at least one of a plurality of available sectors for use in interference cancellation or equalization;
a symbol estimator coupled to the selection module for generating one or more symbol estimates from at least one of the one or more signal paths; and
a receiver module coupled to the symbol estimator for generating a substantially interference cancelled signal;
wherein each of the at least one of the plurality of available sectors continues to be used for symbol estimation unless at least one of an override threshold and a time of override is satisfied.

Abstract
A controller for advanced receivers configures a plurality of advanced receiver modules based on figures of merit computed on the input signal. The controller also selects the appropriate output signal based on figures of merit of either the input or the output signals. The controller decisions can also be made in a bursty manner, where only a subset of the decisions to be made are made at a given time, thereby limiting the processing load of the control processor.

14. A method for signal processing in a mobile station, comprising:
-
receiving a signal in a receiver; detecting one or more signal paths in the signal; selecting at least one of the one or more signal paths and selecting at least one of a plurality of available sectors for use in interference cancellation or equalization; generating one or more symbol estimates from at least one of the one or more selected signal paths; and generating a substantially interference cancelled signal from the one or more symbol estimates; wherein each of the at least one of the plurality of available sectors continues to be used for symbol estimation unless at least one of an override threshold and a time of override is satisfied. - View Dependent Claims (15, 16, 17, 18)
