Shannon's determination of the capacity of the linear Gaussian channel has posed a
magnificent challenge to succeeding generations of researchers. This paper surveys how …

Network information theory promises high gains over simple point-to-point communication
techniques, at the cost of higher complexity. However, lack of structured coding schemes …

We review probabilistic constellation shaping (PCS), which has been a key enabler for
several recent record-setting optical fiber communications experiments. PCS provides both …

A new coded modulation scheme is proposed. At the transmitter, the concatenation of a
distribution matcher and a systematic binary encoder performs probabilistic signal shaping …

In this paper, achievable information rates (AIR) for fiber optical communications are
discussed. It is shown that AIRs such as the mutual information and generalized mutual …

We propose a variable-rate and variable-power MQAM modulation scheme for high-speed
data transmission over fading channels. We first review results for the Shannon capacity of …

This paper deals with 2/sup l/-ary transmission using multilevel coding (MLC) and multistage
decoding (MSD). The known result that MLC and MSD suffice to approach capacity if the …

Variable-rate data transmission schemes in which constellation points are selected
according to a nonuniform probability distribution are studied. When the criterion is one of …

We address an open question, regarding whether a lattice code with lattice decoding (as
opposed to maximum-likelihood (ML) decoding) can achieve the additive white Gaussian …

It is shown that any point in the capacity region of a Gaussian multiple-access channel is
achievable by single-user coding without requiring synchronization among users, provided …
