> IEEE AWPL December 2006 < 1 Abstract--A multiple-input multiple-output (MIMO) system

Summary: > IEEE AWPL December 2006 < 1
Abstract-- A multiple-input multiple-output (MIMO) system
equipped with a new class of antenna arrays, henceforth referred
to as multifunction reconfigurable antenna arrays (MRAAs), is
investigated. The elements of MRAA, i.e., multifunction
reconfigurable antennas (MRAs) presented in this work are
capable of dynamically changing the sense of polarization of the
radiated field thereby providing two reconfigurable modes of
operation, i.e., polarization diversity and space diversity. The
transmission signaling scheme can also be switched between
transmit diversity (TD) and spatial multiplexing (SM). The
results show that the reconfigurable modes of operation of an
MRAA used in conjunction with adaptive space-time modulation
techniques provide additional degrees of freedom to the current
adaptive MIMO systems, resulting in more robust system in
terms of quality, capacity and reliability. A performance gain up
to 30 dB is possible with the proposed system over conventional
fixed antenna MIMO systems depending on the channel
