This paper deals with single-tap equalization for the recently introduced FBMC-PAM system, a multicarrier scheme able to meet the requirements of cognitive radio such as high level of adjacent channel leakage ratio and asynchronous communications. The optimum single-tap gain in the minimum mean square error (MMSE) sense is derived and its performance is compared with that of previously considered receivers. It is shown that, when the zero-mean output of the standard matched filter is noncircular, the proposed equalizer is superior to the existing single-tap alternative solution and comes close in performance to a more advanced previously considered structure.

Abstract
This paper deals with single-tap equalization for the recently introduced FBMC-PAM system, a multicarrier scheme able to meet the requirements of cognitive radio such as high level of adjacent channel leakage ratio and asynchronous communications. The optimum single-tap gain in the minimum mean square error (MMSE) sense is derived and its performance is compared with that of previously considered receivers. It is shown that, when the zero-mean output of the standard matched filter is noncircular, the proposed equalizer is superior to the existing single-tap alternative solution and comes close in performance to a more advanced previously considered structure.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
