Abstract
This article provides a detailed signal model (DSM) based on network theory to predict the multiantenna capacity in the presence of coβ and adjacent channel interference.This model expands on previous channel models by including the simultaneous effects of interference, antenna matching, efficiency, directivity and polarization. Single and multiantenna interference are modeled using both a statistical channel model and a siteβspecific 3D ray tracer. The network theory based DSM was obtained by adding antenna front end effects at both the transmitter and receiver to the channel models. This model was validated with measurements performed in two underground tunnels. The siteβspecific model predicted the capacity to within 1 bit/sec/Hz of the measurements while the statistical model was within 1β2 bits/sec/Hz except for a few locations. It was also observed that for small antenna spacing the conjugate match provides higher capacity than the self match. Β© 2010 Wiley Periodicals, Inc.

## Abstract Interference reduction via a cancellation scheme for synchronous optical CDMA systems is discussed. Based on integrating over one bit duration of the received optical signal, the interfering signals can be estimated and cancelled by the desired correlator. Irrespective of high or low lo
