摘要：The International Telecommunication Union for Radiocommunication (ITU-R) became involved with the spectrum allocation for next generation mobile communication services in World Radio Communication conference 2007 (WRC- 07). The reason is to minimize the adjacent channel interference between Mobile service and DVB-T system within the same geographical area. Therefore, this paper investigates the spectrum sharing requirements such as separation distance and studies the compatibility between Mobile services (IMT-Advanced) and Digital Video Broadcasting � Terrestrial (DVB-T) in the 790 to 862 MHz frequency band. This paper also involves the studies of propagation characteristics within this band which can provide better coverage. Possibility of coexistence and sharing analysis were obtained by taking into account the detailed calculations of the path loss effect by using the practical parameters of DVB-T and Mobile service. The interference has been analyzed and simulated for suburban environment in different channel bandwidths for Mobile service at 5MHz and 20MHz, and in different transmitted power for Digital Video Broadcasting � Terrestrial. The best separation distance between these two systems found are 4.65 Km and 3.42 Km for bandwidth of 5MHz and 20 MHz respectively
