Performance of ISDB-T HDTV Mobile Reception Using 8-branch Space Diversity with Iterative Decoding

Abstract

We are studying how to improve ISDB-T HDTV mobile reception technology. We have proposed a new reception method that has two core technologies. One is 8-branch space diversity reception, and the other is iterative decoding between Viterbi decoding and Reed-Solomon decoding. We describe the computer simulation results and the performance of field experiments on the proposed prototype receiver in the Kanto area. We compared the performance of mobile reception with two reception methods: conventional 4-branch space diversity without iterative decoding and proposed 8-branch space diversity with iterative decoding. Both results show that the proposed method was improved by approximately 6 dB.
