Abstract
A 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. 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 degree of
freedoms to the current adaptive MIMO systems, thereby resulting in more robust system
in terms of quality, capacity and reliability. A substantial performance gain is achievable
