This paper aims to improve the throughput of a broadcasting system that supports the transmission of multiple services with differentiated minimum signal-to-noise ratios (SNRs) required for successful receptions simultaneously. We propose a novel multiplexing method called bit division multiplexing (BDM), which outperforms the conventional time division(More)
Scalable extension to the H.264/AVC video compression standard (SVC) enables one or more subset bit streams (layers) with multiple qualities to be contained in one high-quality video bit stream, which is a good solution for simultaneous transmission of video programs with different qualities. To fulfill the target of scalable video broadcasting (SVB), the(More)
In this paper, a backward compatible multiservice transmission scheme over the digital television terrestrial multimedia broadcasting (DTMB) system is proposed, which is based on embedded constellation and bit division multiplexing. With the proposed scheme, simultaneous transmission of original services and multiple augmented services can be supported in(More)
Non-orthogonal multiple access (NOMA) scheme is a key technique towards the 5th generation (5G) of wireless communication networks due to its higher spectral efficiency comparing to its orthogonal multiple access (OMA) counterpart. However, the complexity of conventional NOMA scheme is extremely high in massive-access scenes. In this paper, we propose a(More)
A two-user Gaussian broadcast channel (GBC) with finite input constellations is addressed in this paper. The constellation-constrained capacity region for the two-user GBC by recently proposed bit-division multiplexing (BDM) is derived. BDM can be seen as a practical implementation of constellation-constrained nonlinear superposition coding (SC). For(More)
An augmented data transmission (ADT) scheme for the Digital Television Terrestrial Multimedia Broadcasting (DTMB) systems based on the technique of embedded constellation is proposed in this paper. With the proposed ADT scheme, the transmission rates of receivers with sufficient good channel conditions are increased at the cost of little impact to the(More)
This paper evaluates the rate loss of fixed-length spatially-coupled low-density parity-check (SC-LDPC) code compared to the asymptotic performance of such code. In previous works, SC-LDPC with sufficient length of codeword shows excellent asymptotic performance and attracts a lot of attentions. However, when the length of codeword is limited, the(More)
To maximize the system throughput for downlink multi-user transmission considering fairness among the users, superposition coding (SC) with all the users scheduled simultaneously is optimal. But it would also lead to high implementation complexity at receivers. In this paper, a simplified downlink multi-user transmission scheme is proposed via combining SC(More)
Scalable video transmission (SVT) system, which is able to transmit video programs with multiple qualities to different users with different channel and reception conditions, is well designed and implemented on FPGA in this paper. The designed SVT system is based on bit division multiplexing (BDM) technique and H.264/SVC. Capacity region analysis, bit error(More)
This paper addresses the performance degradation of near-capacity bit-interleaved coded modulation with iterative demapping and decoding (BICM-ID) when both demapping and decoding employ max-log-MAP algorithm. Two approaches are proposed to overcome the performance degradation: scaling of the transferred log-likelihood-ratios (LLRs) between demapping and(More)
