Abstract

In the context of last mile distribution of broadband interactive services, such as Video on Demand and other applications, a wireless system is proposed in this paper. The 30 GHz band is considered as an allowable spectral resource, and the propagation channel is characterized by means of ray tracing techniques in a reference urban scenario: path loss and frequency selectivity effects are jointly taken into account. A Coded OFDM system with FDM and/or TDM multiplexing schemes is proposed as a suitable method to counteract channel impairments; performance evaluation is analytically derived, and is given in terms of coverage probability and link budget parameters. We emphasize the idea of adaptively deploying the reverse channel (exploited by the user for interactivity purposes) to provide channel informations to the broadcasting transmitter.
