Filter bank multicarrier with PAM modulation for future wireless systems
An efficient transmission system based on the complex lapped transform, running at the same symbol rate as OFDM, is proposed. It does not require a cyclic prefix and, in the multi-user context, it provides a high level of spectral separation between users. A high performance frequency-domain equalizer can be implemented in the receiver in a straightforward manner. The proposed scheme should strengthen the case of FBMC as an alternative to OFDM for asynchronous access in future wireless networks and cognitive radio.
