Dynamic Power Allocation Games in Parallel Multiple Access Channels
Panayotis Mertikopoulos, Elena V. Belmega, Aris L. Moustakas +1
We analyze the distributed power allocation problem in parallel multiple access channels (MAC) by studying an associated non-cooperative game which admits an exact potential. Even…
A trace inequality for positive definite matrices
E. V. Belmega, S. Lasaulce, M. Debbah
In this note we prove that Tr (MN+ PQ)>= 0 when the following two conditions are met: (i) the matrices M, N, P, Q are structured as follows: M = A -B, N = inv(B)-inv(A), P = C-D, Q…
A generalization of a trace inequality for positive definite matrices
E. V. Belmega, M. Jungers, S. Lasaulce
In this note we generalize the trace inequality derived by [1] to the case where the number of terms of the sum (denoted by K) is arbitrary.
Gaussian Broadcast Channels with an Orthogonal and Bidirectional Cooperation Link
E. V. Belmega, B. Djeumou, S. Lasaulce
This paper considers a system where one transmitter broadcasts a single common message to two receivers linked by a bidirectional cooperation channel, which is assumed to be orthog…
On the Base Station Selection and Base Station Sharing in Self-Configuring Networks
S. M. Perlaza, E. V. Belmega, S. Lasaulce +1
We model the interaction of several radio devices aiming to obtain wireless connectivity by using a set of base stations (BS) as a non-cooperative game. Each radio device aims to m…
Interference Relay Channels - Part I: Transmission Rates
Brice Djeumou, Elena Veronica Belmega, Samson Lasaulce
We analyze the performance of a system composed of two interfering point-to-point links where the transmitters can exploit a common relay to improve their individual transmission r…
