Analysis of DVB-H network coverage with the application of transmit diversity
Abstract
This paper investigates the effects of the cyclic delay diversity (CDD) transmit diversity scheme on DVB-H networks. Transmit diversity improves reception and quality of service (QoS) in areas of poor coverage such as sparsely populated or obscured locations. The technique not only provides robust reception in mobile environments thus improving QoS, but it also reduces network costs in terms of the transmit power, number of infrastructure elements, antenna height and the frequency reuse factor over indoor and outdoor environments. In this paper, the benefit and effectiveness of CDD transmit diversity is tackled through simulation results for comparison in several scenarios of coverage in DVB-H networks. The channel model used in the simulations is based on COST207 and a basic radio planning technique is used to illustrate the main principles developed in this paper. The work reported in this paper was supported by the European Commission IST project - PLUTO (physical layer DVB transmission optimization).Citation
