Error performance of maximalratio combining with transmit antenna selection in flat Nakagami-m fading channels

by Zhuo Chen, Zhanjiang Chi, Yonghui Li, Branka Vucetic - IEEE Trans. Wireless Commun , 2009
"... Abstract—In this paper, the performance of an uncoded multiple-input-multiple-output (MIMO) scheme combining single transmit antenna selection and receiver maximal-ratio combining (the TAS/MRC scheme) is investigated for independent flat Nakagami-m fading channels with arbitrary real-valued m. The o ..."

A Simple Transmit Diversity Technique for Wireless Communications

by S. M. Alamouti , 1998
"... This paper presents a simple two-branch transmit diversity scheme. Using two transmit antennas and one receive antenna the scheme provides the same diversity order as maximal-ratio receiver combining (MRRC) with one transmit antenna, and two receive antennas. It is also shown that the scheme may ea ..."

Maximal-Ratio Eigen-Combining for Smarter Antenna Arrays

by Constantin Siriteanu, Steven D. Blostein , 2007
"... In typical mobile wireless scenarios, signals are received with power azimuth angle spectrum (p.a.s.) of variable azimuth angle spread (AS). Therefore, conventional maximum average signal-to-noise ratio beamforming (BF) or maximalratio combining (MRC) may not necessarily be effective in terms of pe ..."
