Title
A proposal of half-symbol parallel combinatory multicarrier modulation for One-Seg service of ISDB-T system
Abstract
One-Seg service is a mobile terrestrial digital audio/video and data broadcasting service in Japan and many other countries. It transmits QPSK modulated symbols to achieve about 416 kbit/s transmission rate for mobile receivers with 428 kHz of bandwidth at UHF band. To further improve the transmission quality and spectrum efficiency, the system design must consider some major issues such as performance degradation from large Doppler shift and small size hardware for receivers which limit the system only to use low-order M-QAM modulation like BPSK or QPSK and small size of power amplifier with a low dynamic range of peak-to-average power ratio (PAPR). To reduce these impacts on the performance of One-Seg service, this paper proposes a BPSK modulated multicarrier system using parallel combinatory (PC) code. The proposed system achieves better BER performance and better PAPR characteristics with a comparable bandwidth efficiency (BWE) compared to that of the corresponding M-QAM modulated OFDM systems.
