Résumé:
The filter bank multicarrier techniques considered
for efficient transmission in communication systems generally
rely on the offset-QAM modulation, which implies doubling
the processing speed in transceivers. In contrast, the scheme
presented here, based on the complex lapped transform, is
running at the same symbol rate as OFDM. It does not require
a cyclic prefix and, in the multi-user context, it provides a high
level of spectral separation between users. In addition, a high
performance per user carrier frequency offset compensation can
be implemented in the receiver in a straightforward manner.
Theoretical derivations are completed by simulations for channel
equalization and carrier frequency offset compensation. With its
reduced computation speed and its level of performance, the
proposed scheme should strengthen the case of FBMC as an
alternative to OFDM for asynchronous access in future wireless
networks and cognitive radio.
