Abstract

This paper discusses optimisation techniques for the design and deployment of future Digital Video Broadcast (DVB) networks that will minimise the complexity and power consumption of end user equipment and enhance the delivery of new broadband services. These techniques are investigated within the framework of the EC funded PLUTO (Physical Layer DVB Transmission Optimisation) project. The main network optimisation techniques include transmit diversity, low cost on-channel repeaters and multiple channel power amplification, receive diversity, efficient network modelling and planning tools and the definition of service scenarios that describe the future use of broadband services in terms of service type and reception conditions
