Among the filter bank multicarrier techniques for efficient transmission in communication systems, the recently proposed FBMC-PAM transceiver exhibits many advantages in comparison with the OFDM system; in particular, it does not require a cyclic prefix and, in the asynchronous multi-user context, it provides a high level of spectral separation among users. However, a performance loss is encountered when operating in hostile multipath channel if the latency of the overall transceiver and the receiver complexity are maintained limited. The equalizer proposed here is aimed at reducing the performance gap between the two systems without resorting to an increase of latency and complexity. Its performance is assessed by computer simulations. The obtained results show that it exhibits a performance improvement in comparison with the standard FBMC-PAM equalizer, significantly reducing the gap with the standard OFDM system when a low-rate transceiver constellation is used.

Abstract

Among the filter bank multicarrier techniques for efficient transmission in communication systems, the recently proposed FBMC-PAM transceiver exhibits many advantages in comparison with the OFDM system; in particular, it does not require a cyclic prefix and, in the asynchronous multi-user context, it provides a high level of spectral separation among users. However, a performance loss is encountered when operating in hostile multipath channel if the latency of the overall transceiver and the receiver complexity are maintained limited. The equalizer proposed here is aimed at reducing the performance gap between the two systems without resorting to an increase of latency and complexity. Its performance is assessed by computer simulations. The obtained results show that it exhibits a performance improvement in comparison with the standard FBMC-PAM equalizer, significantly reducing the gap with the standard OFDM system when a low-rate transceiver constellation is used. Moreover, a reduced complexity version of the proposed equalizer is derived and analyzed.
