Research and Test on Electromagnetic Fields and Mitigation Strategies of Supplement Coverage Equipment of CMMB

Based on the supplement coverage equipment which has been widely used in China recently for new digital television system and CMMB television system, the electromagnetic field and supplement mitigation are studied and tested in this paper. Not only does the paper objectively test the characteristics of electromagnetic field, but also carry out comprehensive studies from the direction of coverage mitigation and pre-reduction of cumulative exposure. We give suggestions of limiting value and system configuration.
