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(More)
Autumn 1996 41 Copyright 1996. Lucent Technologies Inc. All rights reserved. Introduction This paper describes a new point-to-point communication architecture employing an equal number of antenna array elements at both the transmitter and receiver. The architecture is designed for a Rayleigh fading environment in circumstances in which the transmitter does(More)
We investigate the effects of fading correlations in multielement antenna (MEA) communication systems. Pioneering studies showed that if the fades connecting pairs of transmit and receive antenna elements are independently, identically distributed, MEA’s offer a large increase in capacity compared to single-antenna systems. An MEA system can be described in(More)
We investigate robust wireless communication in high-scattering propagation environments using multi-element antenna arrays (MEA’s) at both transmit and receive sites. A simplified, but highly spectrally efficient space–time communication processing method is presented. The user’s bit stream is mapped to a vector of independently modulated equal bit-rate(More)
In this paper, we discuss some of the most basic architectural superstructures for wireless links with multiple antennas: at the transmit site and at the receive site. Toward leveraging the gains of the last half century of coding theory, we emphasize those structures that can be composed using spatially one dimensional coders and decoders. These structures(More)
Recent information theory results have demonstrated the enormous capacity potential of wireless communication systems with multiple transmit and receive antennas. To exploit this potential, a number of space-time architectures have been proposed which transmit parallel data streams, simultaneously and on the same frequency, in a multiple-input(More)
Providing wireless high-speed packet data services for web browsing and streaming multimedia applications will be a key feature in future code-division multiple-access (CDMA) systems. In this paper, we study down-link CDMA schemes for providing such services using multiple antennas at the transmitter and receiver. We propose a generalization of the(More)
