The capacity of the white Gaussian multiple access channel with feedback
TLDR
In this paper a deterministic feedback code is presented for the two-user Gaussian multiple access channel, which is shown to allow reliable communication at all points inside a region larger than any previously obtained.Abstract:
Since the appearance of [10] by Gaarder and Wolf, it has been well known that feedback can enlarge the capacity region of the multiple access channel. In this paper a deterministic feedback code is presented for the two-user Gaussian multiple access channel, which is shown to allow reliable communication at all points inside a region larger than any previously obtained. An outer bound is given which is shown to coincide with the achievable region, thus yielding the capacity region of this channel exactly.read more

A perspective on multiaccess channels
TL;DR: The information theoretic approach and the collision resolution approach to multiaccess channels are reviewed in terms of the underlying communication problems that both are modeling.
A perspective on multiaccess channels
TL;DR: In this paper, the information theoretic approach and the collision resolution approach to multiaccess channels are reviewed in terms of the underlying communication problems that both are modeling, and some perspective on the strengths and weakness of these approaches is given, and the need of a more combined approach focused on coding and decoding techniques is argued.

On the duality of Gaussian multiple-access and broadcast channels
TL;DR: A duality between Gaussian multiple-access channels (MACs) and Gaussian broadcast channels (BCs) is defined, which shows duality under ergodic capacity, but duality also holds for different capacity definitions for fading channels such as outage capacity and minimum-rate capacity.

Recent results in the Shannon theory
TL;DR: The first part of this paper consists of short summaries of recent work in five rather traditional areas of the Shannon theory, namely: source and channel coding theorems for new situations, and calculation of source rate and channel capacity.

A coding scheme for additive noise channels with feedback--I: No bandwidth constraint
J. Schalkwijk,Thomas Kailath +1 more
TL;DR: This paper presents a coding scheme that exploits the feedback to achieve considerable reductions in coding and decoding complexity and delay over what would be needed for comparable performance with the best known (simplex) codes for the one-way channel.

An achievable rate region for the multiple-access channel with feedback
Thomas M. Cover,Cyril Leung +1 more
TL;DR: This region generally exceeds the achievable rate region without feedback and exceeds the rate point found by Gaarder and Wolf for the binary erasure multiple-access channel with feedback.

A coding scheme for additive noise channels with feedback--II: Band-limited signals
TL;DR: This paper extends the scheme for effectively exploiting a noiseless feedback link associated with an additive white Gaussian noise channel to a band-limited channel with signal bandwidth restricted to (- W, W) and achieves the well-known channel capacity.
