Multiple-antennas and isotropically random unitary inputs: The received signal density in closed form
An important open problem in multiple antenna communications theory is to compute the capacity of a wireless link subject to flat Rayleigh block-fading, with no channel-state information available either to the transmitter or to the receiver. The isotropically-random (i.r.) unitary matrix–having orthonormal columns, and a probability density that is invariant to pre-multiplication by an indepen...
متن کاملAnalysis of Aperture Coupled Microstrip Patch Antennas with a Superstrate Using the Space Domain Closed-Form Green`s Functions
Analysis of aperture-coupled microstrip antennas with a superstrate using space domain closed form Greens functions is presented. Integral equations are derived from applying the boundary conditions on the radiating patch, across the aperture, and on the microstrip feedline. The computation of space domain greens functions is performed using the closed-form. The solution of the integral equatio...

متن کاملTransmit Diversity over Quasi-Static Fading Channels Using Multiple Antennas and Random Signal Mapping
We introduce a scheme that achieves a diversity gain for coded systems under static fading conditions by using multiple antennas and random signal mapping. In a two-antenna system, the BER performance of the proposed scheme approaches that of Alamouti’s scheme when the channel is perfectly known. In the presence of channel mismatch, the proposed scheme outperforms Alamouti’s scheme significantl...
متن کاملCapacity of Differential versus Non-Differential Unitary Space-Time Modulation for MIMO channels
Differential Unitary Space-Time Modulation (DUSTM) and its earlier nondifferential counterpart, USTM, permit high-throughput MIMO communication entirely without the possession of channel state information (CSI) by either the transmitter or the receiver. For an isotropically random unitary input we obtain the exact closed-form expression for the probability density of the DUSTM received signal, ...
