TL;DR: A new coded modulation scheme is proposed that operates within less than 1.1 dB of the AWGN capacity 1/2 log2(1 + SNR) at any spectral efficiency between 1 and 5 bits/s/Hz by using only 5 modes.

TL;DR: A transmission system with adjustable data rate for single-carrier coherent optical transmission is proposed, which enables high-speed transmission close to the Shannon limit, and it is experimentally demonstrated that the optical transmission of probabilistically shaped 64-QAM signals outperforms the transmission reach of regular 16- QAM and regular 64-ZAM signals.

TL;DR: Fixed-to-fixed length, invertible, and low complexity encoders and decoders based on constant composition and arithmetic coding are presented and the encoder achieves the maximum rate of the desired distribution, asymptotically in the blocklength.

TL;DR: In this paper, a DVB-S2 low-density parity-check (LDPC) codes were used for bipolar amplitude shift keying (ASK) constellations with equidistant signal points.

TL;DR: In this article, a fixed-to-fixed length, invertible, and low complexity encoders and decoders based on constant composition and arithmetic coding are presented.
