Abstract

In this paper, the scheme that combines LDM(Layered Division Multiplexing) to the BST-OFDM(Band Segmented Transmission - OFDM) is proposed for the next-generation DTTB(Digital Terrestrial Television Broadcasting). In the proposed scheme for fixed reception, the parity-check matrix of the conventional LDPC code whose length is 69120 is extended. After that, the extended parity bits are generated by the parity-check matrix and modulated. These modulated symbols are multiplexed by LDM to symbols for mobile reception. The performances of the proposed scheme are evaluated by computer simulations under AWGN(Additive White Gaussian Noise), and the required CNR(Carrier to Noise Ratio) of fixed reception can be improved by the proposed scheme. Furthermore, it is possible to decode received symbols even with existing receivers that don't support LDM demodulation by using the proposed extended LDPC code for fixed reception.
