Transmitting multiple HD video streams over UWB links

Abstract

Ultra Wide Band technology has attracted a lot of attention recently as a viable solution for high data rate, low power, short-range wireless link. The growing multi-media home networking is demanding more bandwidth and wireless throughput has become a bottleneck for high quality multi-media services. With the maximum data rate above 100 Mbps, UWB is a perfect solution for such applications.This paper describe such a system that takes advantage of the high data rate offered by UWB. We first implemented the complete MB-OFDM PHY layer using multi-FPGA hardware and discrete RF design. Out implementation is fully compliant to the WiMedia/MBOA PHY specifications and the FCC power regulations. The system achieved 110Mbps maximum data rate with a BER better than 10-6 over a range of 4 meters.Subsequently, we developed a testbed that demonstrates simultaneous transmission of multiple High Definition video streams over the MB-OFDM link. The use-case scenario is a Multimedia Client-Server application where we have one Media Server (transmitter) and several Media Players (receivers).

A Measurement-Based Statistical Model for Industrial Ultra-Wideband Channels

“…The first is high-data rate communications, with data rates in excess of 100 Mbit/s [9]. One typical application for such a high-rate system is high-definition TV transmission.…”

Radio-over-Fibre Techniques and Performance

“…The generation of the optical signal to be transmitted in the RoF system is of special difficulty in the case of UWB signals. UWB is a radio technology intended for cable replacement in home applications within a range of tens of meters (picocell range), with high-definition video and audio communications a potential application (Duan et al, 2006). UWB is also attractive in many other applications including medicine, sensor networks, etc.…”

A Synchronization Design for UWB-Based Wireless Multimedia Systems

“…WiMedia, an open industry association, has published a series of standards and its PHY/MAC specification has been adopted by ECMA as an international standard [1]. With a supported data rate up to 480 Mbps, the MB-OFDM UWB link provides sufficient bandwidth to support multiple stream transmission [2]. The transmitter power limit imposed by FCC Part 15 limits the range and bit error performance of all UWB systems.…”
