- W3118134641 abstract "In this paper, we propose a new receiver design for the windowing and restructuring orthogonal frequency division multiplexing (WR-OFDM) system to be robust to the long delay multipath, which is the drawback of the conventional WR-OFDM system. Various windowing techniques can be used to improve the spectral efficiency of OFDM systems. One of them is the WR-OFDM system. This system reduces out-of-band (OOB) power by windowing without increasing the symbol length of OFDM. The system cuts out the cyclic prefix (CP) and data portion of the OFDM symbol through a windowing process, and restores the windowed data portions using the CP portions at the receiver. This method works very well in the additive white Gaussian noise (AWGN) environment, but if a long multipath delay occurs, the CP part used for recovery is damaged, resulting in performance degradation. In this paper, in order to overcome the drawback, the receiving processing unit of the receiver is two ways, and the received signal having excellent signal quality is demodulated. Simulation results show that the proposed system can effectively overcome the drawback of WR-OFDM system." @default.
