1. A method for processing signals, the method comprising: performing by one or more processors and/or circuits in a wireless device comprising a plurality of transmit and/or receive antennas for one or more of HSDPA, space-time transmit diversity (STTD), Closed Loop, Normal Mode and spatial multiplexing, the one or more processors and/or circuits comprising a minimum mean square error (MMSE) equalizer: generating a plurality of chip-rate synchronously sampled signals utilizing a plurality of received clusters; and simultaneously equalizing in time domain and in spatial domain at least a portion of said generated plurality of chip-rate synchronously sampled signals, based on a plurality of weight values calculated for said plurality of received clusters, wherein said plurality of weight values are iteratively computed utilizing a time-based adaptation method.
