Abstract
A Space Time Transmit Diversity (STTD) Decoder includes a physical channel despreader, a delay buffer, an upper processing branch, a lower processing branch and a combiner. The upper processing branch is operable to apply a conjugate of a first channel estimate to the delay buffer symbol output and produce non STTD encoded symbols. The lower processing branch is operable to read delayed delay buffer symbol outputs and apply a conjugate of a second channel estimate when active in the STTD mode. The lower processing branch then may apply an STTD decoder scheme to the delay buffer symbol output to produce non STTD encoded symbols. The combiner then combines the non STTD encoded symbols of the upper processing branch and non STTD encoded symbols of the lower processing branch to produce a single set of non STTD encoded symbols.
