Agile and reliable measures for voice and video transmission are required for extremely highly-public and highly-urgent services by public institutes such as police department, fire department, and emergency medical service. For this purpose, a part of VHF-band was allocated to the public broadband communications (PBB) and a domestic standard of ARIB STD T-103 was standardized for the PBB. ARIB STD-T103-compatible hardware and systems have been already developed and achieved long-range transmission of voice and video in harsh transmission environment such as the mountain area. On the other hand, this ARIB STD T-103-compatible hardware has a problem about its expensive cost. For a further promotion of the PBB system, the reduction of the hardware price becomes important fact. Under such a background, the introduction of TD-LTE system for the VHF-band has been considered in Japan. The LTE system has the potential for application to the long-range communication system at low cost; however, there is no report on the LTE system evaluation in VHF-band PBB environment. In this paper, we investigate the transmission performance of the 5 MHz bandwidth TD-LTE system in conformity to the Japanese VHF-band requirement by evaluating bit error rate (BER) and block error rate (BLER) with several multi-path fading channel models.
