Abstract
This paper provides results on the use of UFMC modulation scheme in MIMO wireless links operating at mmWave frequencies. First of all, full mathematical details on the processing needed to realize a MIMO-UFMC transceiver at mmWave, taking into account also the hybrid analog/digital nature of the beamformers, are given. Then, we propose several reception structures, considering also the case of continuous packet transmission with no guard intervals among the packets. In particular, an adaptive low complexity MMSE receiver is proposed that is shown to achieve very satisfactory performance. A channel independent transmit beamformer is also considered, as as to avoid the need for channel state information at the transmitter. Numerical results show that the proposed transceiver schemes are effective, as well as that the continuous packet transmission scheme, despite increased interference, attains the highest values of system throughput.
