Résumé:
This paper studies two different multiplexing problems
for Device to Device (D2D) asynchronous communications
with different multi-carrier modulations. Several D2D pairs may
be multiplexed on the same Resource Blocks (RB) if they are
jointly able to reach a high Signal to Interference plus Noise
Ratio (SINR). In asynchronous communications, inter-channel
interference (ICI) is present on top of co-channel interference,
and the multiplexing problem can consequently not be split
per RB since RB are no longer orthogonal. In this paper,
we derive the system model that takes into account ICI and
then study the maximum multiplexing problem. Two heuristics
based on the Frobenius and the infinity norms that lead to
lower bounds on the multiplexing gain are proposed. Then, the
maximum sum SINR problem is studied with the infinity norm,
showing that higher rates are achieved with Filter Bank Multi-
Carrier (FBMC) modulation than with Orthogonal Frequency
Multiplexed (OFDM).
