|Issue Date:||2022||Publisher:||Institute of Electrical and Electronics Engineers Inc.||Abstract:||This article proposes a pre-equalization method to remove inter-numerology interference (INI) that occurs in multi-numerology OFDM frame structures of fifth-generation New Radio (5G-NR) and beyond, on the transmitter side. In the literature, guard bands, filters, and interference cancellation methods are used to reduce the INI. In this work, we mathematically model how the INI is generated and show how it can be removed completely for multi-numerology systems by deploying a pre-equalization matrix on the transmitter side. With this pre-equalization method, the need for guard bands and filters is eliminated and spectral efficiency is improved. © 2022 IEEE.||Description:||Huawei;Nokia;pix moving;Samsung;Technology Innovation Institute (TII)
