Abstract
Digital Terrestrial Television Broadcasting(DTTB) System is based on Orthogonal Frequency Multiplex(OFDM) method. As the DTTB system uses the various techniques, for example, the guard intervals, time or frequency intervals and so on, it is expected to have mobile reception capability. However, in the environments which have serious frequency selective fading or in the low signal level areas, the reception characteristics will be degraded. In this paper, we discuss about the mobile reception characteristics of the OFDM signals by using diversity reception technique.
