Abstract

A method and apparatus are provided that uses the feedback information from an ARQ signal that is received to control the transmit diversity of a transmitter. The method provides for improved performance over some existing ARQ plus open loop transmit diversity schemes in terms of bit-error rate for a given Eb/No. Furthermore, the method does not require extra signaling used by closed loop TD schemes.
