ABSTRACT:
A receiver and method for weight detection use received channel estimations and prior feedback information sent to a transmitter to estimate channel weights. The estimated channel weights may have been used by a base station to transmit diversity mode signals. In one embodiment, a trellis algorithm may be used to determine weights with no significant time-slot delay. The weights may be used to generate channel taps for use by a rake receiver in combining multipath components of received signals. In one embodiment, the receiver and method for weight detection may be suitable for use in closed loop diversity mode communication systems, including a Wideband Code Division Multiple Access (WCDMA) system.
