In this paper, we propose a novel non-orthogonal multiple access (NOMA) scheme based on trellis-coded modulation (TCM) techniques. [] Key Method Both codeword design and multi-user detection are considered to optimize the TCM for NOMA. For the NOMA encoder, the multi-dimensional (MD) constellation is carefully selected and a new set partitioning algorithm is developed for MD signal set labeling.

This letter proposes a trellis-coded non-orthogonal multiple access (NOMA) scheme and introduces a joint detection method based on the Viterbi algorithm that outperforms the uncoded NOMA at high signal-to-noise ratio (SNR).

Delayed Bit Interleaved Coded Sparse Code Multiple Access

This work investigates a novel sparse code multiple access (SCMA) scheme called delayed bit-interleaved coded SCMA (DBIC-SCMA), followed by a pre-decoding assisted receiver design which exploits systematic and rate- adapting properties of certain channel codes.

Performance Evaluation of Encoded Opportunistic Transmission Schemes

Due to the exponential decay of the BER curves, coding gain expressions, used in ordinary systems over AWGN, can be used as approximations for opportunistic transmission in fading channels and it is observed that uncoded opportunistic systems are even superior to encoded ordinary ones.
