Abstract :
Antenna (subset) selection is a feasible scheme to reduce the hardware complexity of Multiple-Input Multiple-Output (MIMO) systems. Studies of antenna selection schemes are typically based on channel capacity optimizations employing frequency flat channel models, which are inconsistent with MIMO systems employing spatial-multiplexing. Such systems aim to offer a high data-rate transmission, so that the channel is usually of frequency selective nature. In this contribution we study antenna subset selection at transmitter-and receiver-side for the MIMO Single Carrier (SC) scheme with Frequency Domain Equalization (FDE) in frequency selective channels. As an alternative selection metric the signal quality of the MIMO equalizer output is used.
