EQUALIZATION OF MULTIPLE SIGNALS RECEIVED FOR SOFT HANDOFF IN WIRELESS COMMUNICATION SYSTEMS |
摘要 |
<p>Techniques for performing equalization of multiple signals received by a terminal in soft handoff with multiple base stations. The received signal at the terminal is conditioned and digitized to provide a stream of received samples (y m ), which is then equalized/filtered (410) with multiple sets of coefficients to provide multiple streams of transmit chip estimates (X k ). One set of coefficients (f k ) is provided for each base station and is used to provide a corresponding stream of transmit chip estimates. The multiple streams of transmit chip estimates are further processed (420) to provide multiple streams of data symbol estimates (d k ), one stream of data symbol estimates for each base station. The multiple streams of data symbol estimates are then scaled (430) with multiple scaling factors (± k ) and combined (432) to provide a stream of combined data symbol estimates (d k ). The processing for the multiple base stations may be performed by a single hardware unit in a time division multiplexed manner.</p> |
