Abstract :
This paper considers the combination of space-time codes and macrodiversity to the cellular downlink. The antenna array used by the space-time code is comprised of the antennas of two or three geographically separated base stations. For ease of exposition and to reduce algorithmic complexity, we have restricted our attention to space-time block codes. Simulation results indicate a significant improvement in energy efficiency at remote locations when the proposed system is used
