This paper is motivated by the need for fundamental understanding of ultimate limits of bandwidth efficient delivery of higher bit-rates in digital wireless communications and to also begin to look into how these limits might be approached. We examine exploitation of multi-element array (MEA) technology, that is processing the spatial dimension (not just the time dimension) to improve wireless capacities in certain applications. Specifically, we present some basic information theory results…

The capacity of multiple antenna fading channels is studied on the scenario where the fading coefficients vary quickly; thus an accurate estimation of the coefficients is generally not available to either the transmitter or the receiver.

Recently a number of researchers have pointed out the remarkable Shannon capacity gains available using multielement antennas at both receiver and transmitter of a wireless system, often called multiple-in, multiple-out (MIMO) systems, and devised "space time codes" to achieve some part of these capacities.
