- Abstract
- Ultra-wideband (UWB) technology has offered a large application bandwidth which has been reached up to 1 Gb/s recently. One of various UWB specifications, medium access control (MAC) and physical layer (PHY) technologies of WiMedia Alliance can also be used for high speed multimedia applications to establish a wireless video area network (WVAN). In this paper, we propose a Gb/s UWB video transmission system for WVANs. In order to verify the possibilities of Gb/s wireless transmission of multiple video streams, we first built an analysis model and a simulation model. Then we implemented a hardware-based traffic processing block and a Gb/s wireless MAC accelerator. Using the proposed Gb/s video transmission system, we can transmit high definition video streams to several tens of users while guaranteeing quality of service. © 2011 IEEE.
