Highlights and Novelties


1- This paper studies the behavior of users in a classical Additive White Gaussian Noise Multiple Access Channel (AWGN MAC) with users who are subject to a maximum average power constraint.

2- It provides a curious example of a situation where having more participants does not necessarily lead to worse performance.

3- Our motivating question is how users in an AWGN MAC choose their operating point in the absence of any regulating authority.

4- This is in contrast to the standard communication setup that implicitly assumes that users already agreed on the individual rates.


Manuscript Abstract
In this paper, we study the behavior of users in a classical Additive White Gaussian Noise Multiple Access Channel (AWGN MAC) with users who are subject to a maximum average power constraint. This is one of the simplest multiple-user channel, and its capacity region is known and well defined. It also provides a curious example of a situation where having more participants does not necessarily lead to worse performance. Namely, a user can be added to an AWGN MAC with users in such a way that the rates of the incumbent users stay the same. This is so since the capacity of an AWGN MAC with users is a subset of the capacity region with users. Our motivating question is how users in an AWGN MAC choose their operating point in the absence of any regulating authority. This is in contrast to the standard communication setup that implicitly assumes that users already agreed on the individual rates.
