Cutoff Rate and Outage Probability Performance Comparisons Between DVB-T and DMB-T Systems Under Multipath Channels

摘要

Orthogonal frequency-division multiplexing (OFDM) is extensively used in modern terrestrial digital television broadcasting systems to support high performance bandwidth-efficient multimedia services. Cutoff rate and outage probability are two important criterions to evaluate the performances of a practical communication system in radio engineering. In this paper, the cutoff rate and outage probability performances are compared between two important terrestrial digital television broadcasting systems, the cyclic prefix OFDM based DVB-T system and the time domain synchronous OFDM based DMB-T system, under different multipath channel conditions.
