Performance analysis of transmit and receive antenna selection over flat fading channels
Güçlüoğlu, Tansal; Duman, Tolga M. (IEEE-INST Electrical Electronics Engineers Inc, 2008)The paper considers two different antenna selection schemes for space-time coded systems over flat fading channels. First we explore antenna selection at the transmitter side based on the received signal to noise ratios. ... -
