In order to estimate the link budget for mobile reception of ISDB-T, investigations of the effect of man-made noise and dynamic behavior of field strength are important. Instantaneous variation of field strength has been measured on major roads in Tokyo area. The analysis of short section median show that the minimum usable field strength for UHF broadcasting band and VHF broadcasting band is 40dBμV/m and 49dBμV/m respectively. Moreover comparing a short section median of the digital signal with that of the analog signal, it has been shown that the service area of digital broadcast for mobile reception can be presumed by measuring current analog broadcast signal transmitted from the same point.
