Abstract

In this paper, we analyze the coexistence between the International Mobile Telecommunications (IMT) system and the digital television (DTV) system in the 700MHz band. The 700MHz band is now called the “digital dividend” and is expected to be allocated to IMT services. This plan could cause mutual interference between existing broadcasting and the IMT services. The members in the Asia-Pacific Telecommunity Wireless Group are currently discussing the coexistence issues associated with the 700MHz band. In order to allocate this band to the IMT services without harming the DTV system, coexistence problems should be solved. This paper presents the simulation methodology for analyzing the mutual interference between the IMT and DTV system and provides the results of the performance degradation of the two systems.
