6-8 A study on required C/N in mobile reception for digital terrestrial broadcasting in typical urban model

Abstract

This paper describes the results of indoor experiments for mobile reception of digital terrestrial broadcasting. Distribution of field strength in mobile reception in urban area is very similar to that of GSM Typical Urban Area model. We used this model as the typical propagation model in urban area, and measured required C/N in mobile reception. Experimental results show that the fading margin is about 6dB in the case of DQPSK with 1/2 inner code in the range that maximum Doppler frequency is from 5Hz to 80Hz.
