This paper presents a balanced power control scheme for the uplink of cellular MIMO system. The problem of coordinating power consumption reduce with raise in capacity simultaneously is formulated and an efficient algorithm with good performance is derived. Convex optimization method is used to solve the question. In this paper, an adaptive power allocation scheme is proposed by using interior-point...
When transmitting stochastic traffic flows over wireless networks, there exists an inherent tradeoff between average transmit power and corresponding queuing-delay bound. In this paper, we investigate such a trade-off and show how average power increases as delay-bound requirement becomes stringent. Specifically, we propose the resource allocation schemes to minimize the power consumption subject...
In this article we present various issues that need careful design for the successful implementation of OFDMA-based multihop cellular networks which need incorporation of relay terminals. The first issue we present is synchronization. We show that it is not a problematic issue for infrastructure-based relaying, where the relay is deployed by a system operator at strategic points in the cell. Second,...
