Advanced algorithms to increase wireless network capacity

Novel transmission scheme

Next-generation wireless video services will constitute an exploding market over the next few years. Current cellular and wireless LAN infrastructures are insufficient, however, to support not only the kinds of multimedia streaming traffic that video will require, but also the increasing numbers of subscribers. Since the available resources—power and bandwidth—are limited, the necessary increase in capacity can only come from new, highly advanced algorithms. This project will develop a novel transmission scheme employing very smart multiple antennas. A core component of the scheme is a special “interference canceling” precoder built on advanced algorithms that approach the promised fundamental limits of current network capacity. The nature of the precoder is general in scope and therefore will likely find applications in a variety of information and communication technologies.
