Wilzeck andreas.wilzeck@ikt.uni-hannover.de Received 31 May 2007 Revised 21 September 2007 Accepted 15 January 2008 Recommended by Markus Rupp Antenna subset selection techniques are feasible to reduce the hardware complexity of multiple-input multiple-output MIMO systems while keeping the benefits of higher-order MIMO systems. Many studies of antenna selection schemes are based on frequency-flat channel models which are inconsistent to broadband MIMO systems employing spatial-multiplexing. In broadband MIMO systems aiming to provide high-data-rate links the employed signal bandwidth is typically larger than the coherence bandwidth of the channel so that the channel will be of frequency selective nature. Within this contribution we provide an overview on joint transmitter- and receiver-side antenna subset selection methods for frequency selective channels and deploy them in MIMO orthogonal frequency division multiplexing OFDM systems and MIMO single-carrier SC systems employing frequency domain equalization FDE .

INTRODUCTION The use of multiple antennas at receiver- and or transmitterside that is the so-called multiple-input multiple-output MIMO systems is nowadays an almost mandatory part .
