Ultra wideband receiver based on MB-OFDM modulation

Abstract

Wireless connectivity is now making inroads into the digital home and office systems. In the near future, people will be sharing photos, video, data and voice among networked consumer electronics throughout their digital homes. Yet today's wireless personal area network (WPAN) technologies cannot meet the needs of wireless connectivity among these devices that require high bandwidth for connection and media exchange. This introduces an urgent need of a new wireless technology that is able to support multiple high data rate streams, consume very low power, and maintain low implementation cost. Ultra-wideband (UWB) is one of the emerging technologies that can fulfill these requirements. The enormous bandwidths available, from 3.1 GHz to 10.6 GHz, the potential for the high data rate, and the potential for very low cost operation makes UWB technology a viable candidate for current and future wireless applications. Nevertheless, to fulfill these expectations, UWB research and development has to cope with several design challenges that limit the performance and coverage range of UWB systems.
