Beamforming Versus Transmit Diversity in the Downlink of a Cellular Communications System

B. Friedlander, Stephan Scherzer

Open publisher page 56 citations

Abstract

Transmit diversity and beamforming are two complementary techniques for using multiple antennas in the forward link of a cellular communication system. The first provides the benefit of diversity with no array gain, while the second provides array gain, but no diversity. Here, we present a comparative analysis of the two systems, using outage capacity and transmit power as performance measures. The effects of handoff, correlated fading, and power control are considered.
