6-2 シンボル毎伝送路推定を用いたダイバシティ合成による高速移動受信の検討(第6部門 《テーマ講演》携帯・移動体受信技術)

抄録

In mobile reception of digital terrestrial broadcasting, receiving performance is deteriorated because of channel estimation error caused by receiving level fluctuation under multipath fading environment. We have proposed the diversity reception system using channel estimation by each symbol to improve receiving performance at high speed mobile reception, and experimental results show that the proposed diversity reception system is able to work stably at the 100Hz of the maximum Doppler frequency under the typical urban area propagation environment.
