The multiple-relay channel: coding and antenna-clustering capacity
Michael Gastpar, Gerhard G. Kramer, Piyush Kumar Gupta · 2002
Two coding strategies are developed for a multiple-relay channel having one source terminal and one destination terminal. The first strategy mimics multiple-antenna transmission, while the second strategy mimics multiple-antenna reception. Both approaches are based on the concept of "antenna-pooling" and extend prior art for the single-relay channel. The strategies achieve capacity when the terminals form two closely-spaced clusters.
