Measurement Campaign on Transmit Delay Diversity for Mobile DVB-T/H Systems

This paper describes work carried out by Brunel
University and Broadreach Systems (UK) to quantify the
advantages that can be achieved if Transmit Delay Diversity is
applied to systems employing the DVB standard. The techniques
investigated can be applied to standard receiver equipment
without modification. An extensive and carefully planned field
trial was performed during the winter of 2007/2008 in Uxbridge
(UK) to validate predictions from theoretical modeling and
laboratory simulations. The transmissions were performed in the
730 MHz frequency band with a DVB-T/H transmitter and a
mean power of 18.4dBW. The impact of the transmit antenna
separation and the MPE-FEC was also investigated. It is shown
that transmit delay diversity significantly improves the quality of
reception in fast fading mobile broadcasting applications.
