Abstract :
In this paper, we evaluated the mobile reception performance of ISDB-T receivers using scalable OFDM diversity LSIs. The receivers exploit two kinds of diversity schemes which are time-domain based array antenna (AA) and frequency-domain based carrier diversity (CD). The reception performance of some diversity systems is evaluated by laboratory and field experiments. According to the results, 4ch-CD achieves the highest performance under fading channels. Also, the performance of 4ch-AA is almost as high as that of the 4ch-CD in receiving high-correlated signals, being much better than that of 2ch-CD.
