REPEATER HAVING DUAL RECEIVER OR TRANSMITTER ANTENNA CONFIGURATION WITH ADAPTATION FOR INCREASED ISOLATION
First Claim
1. A repeater for a wireless communication network, the repeater including a reception antenna and first and second transmission antennas, the repeater comprising:
- a weighting circuit for applying a weight to at least one of first and second signals on first and second transmission paths coupled to the first and second transmission antennas, respectively; and
a control circuit configured to control the weighting circuit in accordance with an adaptive algorithm to thereby increase isolation between a reception path coupled to the reception antenna and the first and second transmission paths.

Abstract
A repeater for a wireless communication network includes a reception antenna and first and second transmission antennas. The repeater also includes a weighting circuit which applies a weight to at least one of first and second signals on first and second transmission paths coupled to the first and second transmission antennas respectively, and a control circuit configured to control the weighting circuit in accordance with an adaptive algorithm to thereby increase isolation between a reception path coupled to the reception antenna and the first and second transmission paths.
