An application of smart antenna systems for archiving networks in TV studios

摘要

Data archiving networks and electronic media libraries for video and audio broadcasting have gained a large interest recently. This paper proposes the use of smart (adaptive) antennas for HIPERLAN/2 (HIgh PERformance Radio Local Area Network/2) in order to increase the data rate and user capacity targeting wired LAN replacement in modem TV broadcasting studio environments. Spatial channel models are necessary for the proper design, analysis and implementation of smart antenna systems. A simple 2D ray tracing indoor channel model for predicting propagation characteristics inside a room of arbitrary dimensions and wall properties is presented. The simulation model gives fast estimates of the power-delay profile (PDP) and direction of arrival (DOA) information based on the geometrical optics (GO) theory taking into account double reflections. The effects of the relative positions of the transmitter and the receiver, room dimensions as well as the number of transmitters are investigated.
