Decoding method for Alamouti scheme with HARQ and/or repetition coding

A system for decoding a signal vector in a transmit diversity scheme, comprising:

• means for receiving multiple sets of signals corresponding to common transmitted information, wherein each of the multiple sets of signals is associated with its own channel information and comprises signals associated with different symbol periods;
• means for processing each of the multiple sets of signals and its associated channel information to produce a plurality of signal vectors and a plurality of effective channel matrices;
• means for combining the signal vectors into a combined signal vector, wherein the means for combining comprises means for processing each of the signal vectors based on a corresponding one of the effective channel matrices;
• means for combining the effective channel matrices into a combined effective channel matrix;
• and
• means for decoding the combined signal vector using the combined effective channel matrix.

A receiver for decoding a signal vector in a transmit diversity scheme, comprising:

• one or more inputs for receiving multiple sets of signals corresponding to common transmitted information, wherein each of the multiple sets of signals is associated with its own channel information and comprises signals associated with different symbol periods;
• processing circuitry for:
• processing each of the multiple sets of signals and its associated channel information to produce a plurality of signal vectors and a plurality of effective channel matrices;
• combining the signal vectors into a combined signal vector, wherein the combining comprises processing each of the signal vectors based on a corresponding one of the effective channel matrices;
• and
• combining the effective channel matrices into a combined effective channel matrix;
• and
• a decoder for decoding the combined signal vector using the combined effective channel matrix.
