On the Capacity of Radio Communication Systems with Diversity in a Rayleigh Fading Environment

Is Orbital Angular Momentum (OAM) Based Radio Communication an Unexploited Area?

“…We start by identifying the conditions under which electromagnetic waves with specific OAM characteristics 1 are generated in [1] [2] and continue by comparing with properties of traditional communication using multiple-in-multiple-out (MIMO) antenna systems [5] [6] [7]. We pay special attention to the singular value decomposition (SVD) based derivation of channel capacity for MIMO systems [8], when applied to MIMO systems under free-space propagation conditions.…”

Mimo Capacity in Uwb Channels in an Office Environment for Different Polarizations

“…Multiple-Input Multiple-Output (MIMO) systems are considered one of the best techniques to optimize the use of the transmission spectrum and power [3,4]. This technique benefits from the use of multiple n-dimensional antennas [5] at both sides of the radio interface, so that by using a proper space-time code, either the diversity and/or the throughput can be substantially improved [6].…”

Convergence of DSRC and WiMAX Technology for Intelligent Transportation System

“…The system capacity can be significantly improved if multiple transmit and receive antennas are used to form MIMO channels [12]- [15]. The system proceeds with the deployment of WIMAX unit as it helps to cover the intended coverage area nearly a range of approximately the size of a city.…”
