Cooperative reception diversity apparatus and method based on signal point rearrangement or superposition modulation in relay system
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.

讨论了一种基于在中继站执行的信号点重排和叠加调制提供协同接收分集的方法和装置。 第一技术在中继站进行叠加调制，第二技术在中继站采用信号点重排。 叠加调制是与信号发射机采用的叠加调制不同的叠加调制方式。 类似地，信号点重排是与信号的发射机采用的不同类型的信号点重排。 作为由中继站执行的叠加调制或信号点重排的结果，改善了由目的地接收机处的接收单元接收的信号的可靠性。
