Résumé:
This paper studies the weighted sum rate maximization
problem for device-to-device (D2D) underlay communications.
Since each D2D transmitter is synchronized with its
receiver, all D2D receivers get asynchronous interference from
the other transmitters, and so does the Base Station (BS). This is
modelled by a uniformly-distributed timing offset which generates
inter-channel interferences in multi-carrier transmissions.
Filter Bank based Multi-Carrier (FBMC) is then far more
efficient than Orthogonal Frequency Division Multiplex (OFDM)
to limit the inter-channel interference spread. In this context, D2D
pairs are clustered through graph coloring in order to avoid high
interference situations. Then we derive the weighted sum rate
maximization algorithm with inter-channel interference and with
an interference constraint at the BS. An iterative implementation
of this algorithm converges to the global optimal solution, when
the high Signal-to-Interference-plus-Noise Ratio (SINR) condition
holds. Simulation results show that D2D users can be efficiently
multiplexed, achieving high data rates while fulfilling the BS
interference constraint.
