| Abstract(in English) | To improve the spectral efficiency of the 5th generation mobile communication system (5G) and beyond, the universal time-domain windowed orthogonal frequency division multiplexing (UTW-OFDM) has been proposed. Particularly, the simplified UTW-OFDM is highly compatible with the conventional CP-OFDM. It can strongly suppress out-of-band emission (OOBE) with a simple configuration of multiplying a time window with a long transition length. However, in the UTW-OFDM, multiplication of the time window causes inter-carrier interference (ICI), which degrades the communication quality, especially for higher-order modulation schemes such as 64QAM. In this report, firstly we investigate the applicability of the simplified UTW-OFDM to the 5G. Next, a method is proposed to cancel the ICI caused by the UTW in 5G. In the proposed method, an optimal ICI cancellation weight is designed by taking the noise enhancement suppression into account. The proposed method improves the communication quality while achieving a stronger OOBE suppression. |
