A Study of the influence of the singl ecarrier interference on the OFDM transmission of Digital Terrestrial Television Broadcasting

Abstract

Digital Terrestrial Television Broadcasting(DTTB) system adopted in Japan uses Orthogonal Frequency Division Multiplexing(OFDM) modulation, and the bit error rate varies from the frequency of single carrier interference. The infuence of the single carrier interfence on the OFDM transmission of Digital Terrestrial Television Broadcasting has not been sufficiently clarified. In this paper, the influence of the single carrier interference on the OFDM transmission is experimentally studied, and findings obtained are described below.
