Résumé:
In this paper, we propose a resource allocation
of device-to-device (D2D) communications underlaying cellular
systems by employing message-passing algorithm. It is possible
to construct the factor graph of the D2D pairs by considering
the interference at the base station and among the D2D pairs.
The goal is to avoid interfering the cellular transmission while
increasing the sum data rate of D2D pairs. We show that the
proposed resource allocation based on message passing algorithm
allow us to almost reach the performance of the exhaustive search
and outperforms the random allocation. Since the associated
factor graph is not fully connected, the complexity of the
algorithm is significantly reduced compared to the exhaustive
search.
