ABSTRACT:
A spatial transmit diversity method includes transmitting data at a selected rate from a first antenna and awaiting an acknowledgement indicating successful receipt by the receiving terminal of the data transmitted at the selected rate from the first antenna. The data are then transmitted at the selected rate from a second antenna upon failure to receive an acknowledgement of successful receipt by the receiving terminal of the data transmitted at the selected rate from the first antenna within a predetermined time interval.
