摘要： A method and apparatus for method for providing cooperative reception diversity based on signal point rearrangement and superposition modulation performed at a relay station is discussed. A first technique performs superposition modulation at a relay station and a second technique employs signal point rearrangement at a relay station. The superposition modulation is a different type of superposition modulation than that employed by the transmitter of the signal. Similarly, the signal point rearrangement is a different type of signal point rearrangement than that employed by the transmitter of the signal. As a result of the superposition modulation or signal point rearrangement performed by the relay station, the reliability of a signal received by a reception unit at the destination receiver is improved.
