Abstract
We are studying on improvement of ISDB-T HDTV mobile reception for expanding reception area, such as the space diversity technology up to 4-branch and directional diversity technology. In this paper, we describe the performance of two technologies adopted reception scheme by computer simulation. One is 8-branch space diversity reception technology, and the other is iterative decoding technology between Viterbi decoding and Reed-Solomon decoding. Comparing the performance of the proposed 8-branch space diversity technology with iterative decoding to that of the conventional 4-branch space diversity without iterative decoding in mobile reception environment, about 4dB is improved by space diversity technology, about 2dB is improved by the iterative decoding, and totally about 6dB is improved by the combined technology.
