In wireless systems, a method and system for pre-equalization in a single
weight (SW) single channel (SC) multiple-input multiple-output (MIMO)
system are provided. A first receive antenna and at least one additional
receive antenna may receive a plurality of SC communication signals
transmitted from at least two transmit antennas. Estimates of the
propagation channels between transmit and receive antennas may be
performed concurrently and may be determined from baseband combined
channel estimates. Channel weights may be determined to modify the
signals received by the additional receive antennas. Pre-equalization
weight parameters may be determined to modify subsequent signals
transmitted from the transmit antennas. The pre-equalization weight
parameters may be based on the propagation channel estimates and may be
determined by LMS, RLS, DMI, or by minimizing a cost function. Closed
loop transmit diversity may also be supported.
