In this paper we consider the problem of data rate maximization of wireless users in multicarrier system in the context of game theory. In such a game, each user maximizes its data rate over all subcarriers while keeping its total transmit power bellow a given threshold. To control the selfish behavior of users we propose a new pricing mechanism whose value depends on transmit power of user as well...
When rate expectations of users in a wireless network cannot all be satisfied, one choice is to discard some users from the system, in a mechanism called admission control. However, in a data network, users have a certain tolerance to occasional rate outages. In this paper we argue that it may be preferable for users to reduce their rate objectives smoothly, by considering an outage probability tolerance,...
In this two-part paper, we address the problem of finding the optimal precoding/multiplexing scheme for a set of noncooperative links sharing the same physical resources, e.g., time and bandwidth. We consider two alternative optimization problems: P.l) the maximization of mutual information on each link, given constraints on the transmit power and spectral mask; and P.2) the maximization of the transmission...
