In this paper we consider multi-user multicarrier
transmissions with flexible subcarrier spacings. In a scenario of
multiple users access with different subcarrier spacings the orthogonality between subcarriers is disrupted. The paper presents
the Intercarrier Interference (ICI) that occurs between two
users with different subcarrier spacings in a Universal Filtered
Multicarrier (UFMC) system. We investigate the interference
induced by one user to another. We propose closed form functions
for ICI for both users and validate them with simulation results.
Also, we provide simulation results of the ICI power in terms of
filter lengths and number of guard subcarriers and we calculate
the corresponding achieved time-frequency efficiencies.
