Equal allocation of bandwidth and/or power may not be efficient for wireless multi-user networks with limited bandwidth and power resources. Optimal joint bandwidth and power allocation strategies for wireless multi-user networks with and without relaying are proposed in this paper for (1) the maximization of the sum capacity of all users; (2) the maximization of the worst user capacity; and (3) the...
Joint bandwidth and power allocation in wireless multi-user decode and forward relay networks is proposed in this paper for maximizing the number of admissible users. A suboptimal greedy search algorithm is developed to solve the admission control problem efficiently at low complexity. The condition under which the greedy search is optimal is found. The way we derive such optimality condition for...
The resource allocation problem in wireless multi-user decode-and-forward (DF) relay networks is considered. The conventional resource allocation schemes based on the equal distribution of bandwidth and/or power may not be efficient for the networks with constrained/limited power and bandwidth resources at both sources and relays. Therefore, joint bandwidth and power allocation schemes are proposed...
