This paper addresses the problem of resource allocation
in a multiple access channel where several mobile terminals
(MT’s) are transmitting simultaneously to a single receiving
base station, all of them with multiple antennas and exploiting
beamforming. A multi-carrier modulation is assumed, either
orthogonal frequency division multiplexing (OFDM) or filter
bank multi-carrier (FBMC). The main advantage of FBMC is
that the spectrum of the sub-channels is much more concentrated
than for OFDM. This property is explicitly exploited in this
paper in order to evaluate an asynchronous network where
the transmissions from different MT’s are not aligned in time.
This implies that a frequency guard between groups of carriers
assigned to different users has to be included, being larger for
OFDM than for FBMC. The improvement in performance due to
this fact is evaluated by means of the rate that can be achieved
by dynamically allocating carriers to users and by calculating
the power and bit loading to be applied.
