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.
