  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 how it can be removed completely for multi-numerology systems on
the transmitter side.
