The successor to the DVB-H broadcast handheld standard (DVB-NGH) is currently being defined by the DVBTM- H working group. A key feature which would distinguish the new standard from the old is the likely inclusion of cross-polar transmission and reception for increased capacity and robustness through twin-antenna MIMO schemes. To enable simulations of the various proposals to be carried out, a channel sounding campaign took place in July 2010 in Helsinki, Finland, focussing on cross-polar UHF transmission and reception. A number of practical designs for antennas suitable for a handheld terminal were included in the trial and all test data was obtained via these devices. Following the campaign, analysis of the data has produced a simple model for both outdoor and indoor scenarios of the antennainclusive 2-by-2 channel.

This paper briefly describes the excitation signal and test arrangements before introducing the form of the channel model. Finally the actual parameters of the model which have resulted from the measurements are discussed and related to the likely observable behaviour of the NGH cross-polar signal
