Abstract
The present invention provides techniques to determine an antenna selection and associated weights for a transmission system having multiple antennas. A receiver first samples signals received on each antenna and the channel characteristics for each received signal is calculated. The signal-to-interference-plus-noise (SINR) ratio for various combinations of antennas is estimated using the channel characteristics and a subset of antennas and accompanying weights are determined that can provide an advantageous SINR.
