On the Capacity of Wireless Systems Employing OFDM-Based Spatial Multiplexing
Overview This paper computes the capacity of wireless Orthogonal Frequency Division Multiplexing (OFDM)-based spatial multiplexing systems in delay spread environments. Introducing an abstract model to characterize the statistical properties of the space-time channel, it provides Monte-Carlo methods for estimating the capacity cumulative distribution function, expected capacity, and outage capacity of the OFDM-based spatial multiplexing system for the case where the channel is unknown at the transmitter and perfectly known at the receiver. The paper provide bounds on capacity, and it studies the influence of physical parameters such as the amount of delay spread, angles of arrival, scattering radius, and line-of-sight component, and system parameters such as the number of antennas and antenna spacing on capacity.
