Abstract
Interference reduction is achieved within a communication device using a low complexity antenna array. In at least one embodiment, phase and magnitude values associated with an antenna element within a low complexity array are dynamically adjusted during device operation in a manner that enhances a predetermined quality criterion (e.g., SINR).
Claims20
A method for reducing interference in a communication device comprising:
- providing a communication device having first and second antenna elements, said first antenna element having an adjustable weight;
- applying a predetermined weight to said first antenna element;
- estimating a combined channel response for said first and second antenna elements while said predetermined weight is being applied for a first base station of interest;
- calculating individual channel responses for channels between said first and second antenna elements and said first base station of interest using said estimated combined channel response;
- and
- determining a new weight for said first antenna element that enhances an interference-related quality criterion using said individual channel responses.

A method for reducing interference in a communication device comprising:
- providing a communication device having first and second antenna elements, said first antenna element having an adjustable weight;
- applying a predetermined weight to said first antenna element during a present time period;
- estimating a combined channel response for said first and second antenna elements while said predetermined weight is being applied for a first base station of interest;
- calculating individual channel responses for channels between each of said first and second antenna elements and said first base station of interest for said present time period using said combined channel response;

- and
- applying said new weight to said first antenna element during said present time period.
4 more elements
A communication device comprising:
- first and second antenna elements, said first antenna element having an adjustable weight;
- a combiner to combine outputs of said first and second antenna elements to generate a combined signal;
- and
- a controller to control said adjustable weight of said first antenna element, said controller including:
- a first unit to determine individual channel responses for said first and second antenna elements for each of a plurality of base stations of interest;
- and
- a second unit to determine a weight for said first antenna element that optimizes an interference-related quality criterion using the individual channel responses.
