MIMO Systems with Antenna Selection

by Andreas F. Molisch, Moe Z. Win , 2004
"... Multiple-input–multiple-output (MIMO) wireless systems are those that have multiple antenna elements at both the transmitter and receiver [1]. They were first investigated by computer simulations in the 1980s [2], and later papers explored them analytically [3], [4]. Since that time, interest in MIM ..."

Interference Cancellation in MIMO Systems

by Zoltán Németh, Sándor Imre
"... Abstract-- The MIMO systems have many advantages compared to single transmissions. However, the interference load is increased, causing difficulties in transmission. A possible solution for the problem is provided by the BSS, which is an application of ICA. The two main classes of ICA algorithms (th ..."

MIMO systems with adaptive modulation

by Zhendong Zhou, Student Member, Branka Vucetic, Mischa Dohler, Yonghui Li - IEEE Transactions on Vehicular Technology , 2005
"... Abstract—Adaptive modulation (AM) schemes in multiple in-put multiple output (MIMO) systems with a perfect or imperfect channel state information (CSI) at both the transmitter and re-ceiver were investigated. Under an average transmit power and instantaneous bit error rate (BER) constraint, the tran ..."

Superdirectivity in MIMO systems

by Michael A. Jensen, Matthew L. Morris, Michael A. Jensen, Matthew L. Morris, Jon W. Wallace, Matthew L. Morris, Michael A. Jensen, Senior Member, Jon W. Wallace - IEEE Trans. Antennas Propagat , 2005
"... Abstract—Multiantenna systems such as devices for mul-tiple-input–multiple-output (MIMO) communication can the-oretically use array superdirectivity to optimally exploit the propagation channel. In traditional analyses of MIMO systems, such superdirectivity is not observed due to the commonly applie ..."
