Abstract
A novel filter bank based multicarrier (FBMC) transmission scheme is proposed, where the transmit antennas are employed to substantially reduce the inherent inter-carrier and inter-symbol interference. Since FBMC systems do not apply a guard interval, they can achieve higher spectral efficiencies than OFDM systems, although at the cost of additional inter-symbol interference (ISI). In this paper, we present a method which reduces the number of interference terms by employing a multiantenna precoding scheme based on spatial diversity, and the system can benefit from the multiuser gain, through an opportunistic scheduler at the transmitter side.
