Bit-interleaved coded modulation in the wideband regime [PDF]
, 2007 The wideband regime of bit-interleaved coded modulation (BICM) in Gaussian channels is studied. The Taylor expansion of the coded modulation capacity for generic signal constellations at low signal-to-noise ratio (SNR) is derived and used to determine ...

A Novel Concatenated Coded Modulation Based on GFDM for Access Optical Networks
IEEE Photonics Journal, 2018 In this paper, we proposed a novel concatenated coded modulation composed of adaptive turbo code with trellis-coded modulation (ATTCM) that is based on generalized frequency division multiplex (GFDM) system.

Improving the performance of BICM-ID and MLC systems with different FEC codes [PDF]
Advances in Radio Science, 2013 In bandwidth limited communication systems, the high data rate transmission with performance close to capacity limits is achieved by applying multilevel modulation schemes in association with powerful forward error correction (FEC) coding, i.e.

Protograph-Based LDPC Code Design for Shaped Bit-Metric Decoding [PDF]
, 2015 A protograph-based low-density parity-check (LDPC) code design technique for bandwidth-efficient coded modulation is presented. The approach jointly optimizes the LDPC code node degrees and the mapping of the coded bits to the bit-interleaved coded ...

Scaling Analysis of Multilevel Polar Coded Modulation
IEEE Access, 2019 In this paper, we analyze and prove the capacity-achieving property of the equivalent asymmetric channels of multilevel polar-coded modulation in view of the scaling assuming regime, which employ some techniques of symmetric channels.

On the Asymptotic Performance of Bit-Wise Decoders for Coded Modulation [PDF]
, 2013 Two decoder structures for coded modulation over the Gaussian and flat fading channels are studied: the maximum likelihood symbol-wise decoder, and the (suboptimal) bit-wise decoder based on the bit-interleaved coded modulation paradigm. We consider a 16-
