This paper provides results on the use of the Universal Filtered MultiCarrier (UFMC) modulation scheme in multiple-input-multiple-output (MIMO) wireless links operating at millimeter wave (mmWave) frequencies. After having provided mathematical details on the MIMO-UFMC signal model, taking into account both the hybrid analog/digital nature of the beamformers and the phase noise (PN) at the receiver, we propose adaptive algorithms, based on the normalized least-mean-squares (NLMS) and on the recursive-least-squares (RLS), for low-complexity data-detection. The proposed transceiver also includes a channel independent transmit beamformer, so as to avoid the need for channel state information at the transmitter, as well as a transmission format wherein no spacing between consecutive data packets is adopted, in order to have increased spectral efficiency. Numerical results show that the proposed algorithms exhibit a certain amount of robustness to the PN and achieve satisfactory performance.

Abstract
This paper provides results on the use of the Universal Filtered MultiCarrier (UFMC) modulation scheme in multiple-input-multiple-output (MIMO) wireless links operating at millimeter wave (mmWave) frequencies. After having provided mathematical details on the MIMO-UFMC signal model, taking into account both the hybrid analog/digital nature of the beamformers and the phase noise (PN) at the receiver, we propose adaptive algorithms, based on the normalized least-mean-squares (NLMS) and on the recursive-least-squares (RLS), for low-complexity data-detection. The proposed transceiver also includes a channel independent transmit beamformer, so as to avoid the need for channel state information at the transmitter, as well as a transmission format wherein no spacing between consecutive data packets is adopted, in order to have increased spectral efficiency. Numerical results show that the proposed algorithms exhibit a certain amount of robustness to the PN and achieve satisfactory performance.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
