- For Eureka-147-based digital audio broadcasting (DAB) system, frequency band III has been generally used in many countries. However, in some countries, other legacy broadcasting services have been adopted in the same frequency band. Especially, in South Korea, T-digital multimedia broadcasting (DMB) service has been already broadcasted through the band III since early 2005. In this paper, to adopt the DAB system in band III, channel allocation method and interference analysis are investigated for Korea broadcasting environment with legacy T-DMB. To allocate DAB channel, actual FM radio broadcasting stations and geographical features are considered. Furthermore, interference analysis and evaluation are performed between co-channel broadcasting areas and adjacent channel broadcasting areas. These evaluation results provide the DAB service channel allocation method in broadcasting environment with legacy broadcasting system, and can be used as a reference to determine the DAB service channel allocation through the frequency band with existing broadcasting system.
