Abstract: In a method for wireless data communication between a base station and a subscriber unit in a wireless communication system, groups of symbols of an input data stream are commutated to produce a plurality of commutated data streams. The plurality of commutated data streams are then transformed to produce a plurality of transformed data streams. Next, each transformed data stream is spread with a selected one of a plurality of spreading codes to produce a plurality of antenna signals. Finally, each of the plurality of antenna signals is transmitted using a selected one of a plurality of spaced apart antennas, wherein the plurality of spaced apart antennas are spaced apart to provide transmit diversity. In one embodiment, the transform is a space-time transform.

Abstract: A space time transmit diversity scheme using two antennas (9, 10) in which a data block of symbols (D22) is transmitted simultaneously with a complex conjugate of another block (D21*). With suitable receiver (15) processing, t he symbols can be recovered with only a small complexity increase. The inventio n has a particular application to CDMA systems operating in TDD mode.

Abstract: A multi-receiver wireless communication device includes a transmitter, a transmit oscillator communicatively coupled to the transmitter, a receive oscillator communicatively coupled to a first receiver and second receiver, and a switching assembly having a first state in which the receive oscillator is coupled to the first and second receivers and a second state in which the receive oscillator is de-coupled from the second receiver and the transmit oscillator is coupled to the second receiver. The first receiver and the second receiver of the wireless communication device are able to operate independent of one another when the switching assembly is in the second state.

Abstract: In a method for wireless data communication between a transmitter and a receiver in a wireless communication system, groups of symbols of an input data stream are commutated (24) to produce a plurality of commutated data streams. The plurality of commutated data streams are then transformed to produce a plurality of transformed data streams. Next, each transformed data stream is spread (26, 28) with a selected one of a plurality of spreading codes to produce a plurality of antenna signals. Finally, each of the plurality of antenna signals is transmitted using a selected one of a plurality of spaced apart antennas (34, 36), wherein the plurality of spaced apart antennas (34, 36) are spaced apart to provide transmit diversity. In one embodiment, the transform is a space-time transform.
