METHOD IN A WIRELESS REPEATER EMPLOYING AN ANTENNA ARRAY INCLUDING VERTICAL AND HORIZONTAL FEEDS FOR INTERFERENCE REDUCTION

摘要

An echo cancellation wireless repeater with first and second antenna arrays having vertical and horizontal feed antenna elements selects a combination of antenna elements for reception and transmission to reduce interference and improve the quality of signal reception. In one embodiment, the antenna elements are switchably connected to transceiver circuits and a combination of antenna elements is selected based on the best desired performance result. In another embodiment, the antenna elements are each connected to its own transceiver circuit and the echo cancellation repeater performs beamforming in baseband to select a combination of antenna elements.
