11. A system for handling wireless communication, the system comprising:
a first receive antenna and at least one additional receive antenna that enables receipt of pre-equalized single channel (SC) current communication signals generated based on previously communicated pre-equalization weight parameters corresponding to signals previously received by at least one of said first receive antenna and said at least one additional receive antenna;
a single weight baseband generator (SWBBG) that enables determination of a plurality of current channel estimates based on said received pre-equalized SC current communication signals;
said SWBBG enables determination of a plurality of channel weights based on said determined plurality of current channel estimates; and
said SWBBG enables generation of a plurality of signals that modify pre-equalized SC subsequent communication signals received via said at least one additional receive antenna based on said determined plurality of channel weights.
