An Efficient Urban Digital Video Broadcasting (DVB) from Aerial Platforms using Smart Antenna Arrays

Abstract: In this paper, an efficient smart adaptive antenna technique is proposed for the provision of digital video broadcasting services from aerial platforms for urban areas. The proposed smart antenna array utilizes concentric circular arrays with adaptive feeding for maximizing the signal at ground users. The array footprint from aerial platforms is analysed over the whole coverage from aerial platforms showing the link performance in terms of bit-energy to noise power spectral density ratio. The concentric circular array is optimized for providing uniform coverage over wide areas with line-of-sight propagation quality like satellite DVB systems but at very close range for both fixed and mobile stations.
