Abstract
At least two passive antenna arrays of an existing multicarrier base station transceiver system are supplemented by an auxiliary antenna array to provide a system and method of enhancing reverse link sensitivity and reducing the effects of multipath fading in a wireless communication system without the need for modifications to the mobile station. The auxiliary antenna array provides a complementary transmit diversity path for the two passive antennas such that a predetermined time delay is implemented to a composite transmit signal and the delayed composite transmit signal is fed directly to the auxiliary antenna array. The delayed signal and the signals from the passive antenna arrays provide a reduced noise figure and time delay transmit diversity for the multicarrier BTS operation.
