The scheme that combines LDM(Layered Division Multiplexing) to the BST-OFDM(Band Segmented Transmission – OFDM) has been proposed for the next-generation DTTB(Digital Terrestrial Television Broadcasting). In this paper, the scheme that can decode received symbols even with conventional receivers that don’t support LDM demodulation for fixed reception is proposed. 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. In this paper, we studied improvement of extended parity generation for LDM-BST-OFDM, and the performances of the proposed scheme are evaluated by computer simulations under AWGN(Additive White Gaussian Noise) environment. From the results of simulations the required CNR(Carrier to Noise Ratio) of fixed reception can be improved by the proposed scheme. |
