摘要：
This Letter proposes a symbol cyclic reconstruction scheme for universal-filtered multi-carrier (UFMC) systems. In this scheme, the overlap-add technique is employed to reduce the computational complexity of the system transmitter. At the receiver, ISI cancellation is performed to remove the interference between neighbouring overlapped symbols. Then, a cyclic reconstruction algorithm is proposed to eliminate the interference caused by the linear shift. This scheme effectively improves the transmission efficiency in multipath channel environments while ensuring the bit error rate performance. Simulation results show that the TE of the proposed scheme is much higher than that of standard UFMC and cyclic prefix -OFDM systems.
