Novel Radio Channel Models for Evaluation of DVB-H Broadcast Systems

Abstract

A new area of digital television broadcasting has emerged in the from of hand held reception. This has created a need for new standard channel models, which describe more accurately the conditions in portable reception. Hence, the Finnish partners of the multinational CELTIC Wing-TV project performed a comprehensive measurement campaign during autumn 2005. The analysis of the measurement results show that in most scenarios a strong specular or line-of-sight component is present and clearly dominating. This is noted from the very large values of Rician K-factor. The SFN characteristics of the DVB-H reception is clearly visible while considering the RMS delay spreads, total excess delays and variations of the number of taps. Based on the analysis of the measured data this contribution presents novel tapped delay line (TDL) channel models suitable for DVB-H testing
