Description
Summary:In this paper, the scheme that combines LDM (Layered Division Multiplexing) with the FDM (Frequency Division Multiplexing) scheme based on BST-OFDM (Band Segmented Transmission - Orthogonal Frequency Division Multiplexing) is proposed for the next-generation DTTB (Digital Terrestrial Television Broadcasting). The proposed LDM-BST-OFDM scheme provides a more effective frequency utilization of the stream for fixed reception. The performance of the proposed scheme is evaluated by computer simulations where the effectiveness of proposed scheme for fixed reception is shown. Although LDM-BST-OFDM improves the performance, dedicated receivers that can demodulate symbols multiplexed by LDM are required. In this paper, LDM-BST-OFDM using punctured LDPC code is proposed, which can decode the stream for fixed reception even if symbols multiplexed by LDM are not demodulated. The reception characteristics of the proposed scheme are evaluated by computer simulations.
