In this paper we present an overview of various kinds of interference, that arise in the Orthogonal Frequency-Domain Multiplexing (OFDM)-based digital communications systems at the physical layer. Inter-symbol, inter-block, inter-carrier interference types are described in detail, valid for any OFDM transmission, along with Inter-cell interference specific to cellular networks. A survey of various communication disruptions techniques is presented - primarily focusing on intentional interference - jamming. Furthermore, we present a survey of modulation techniques that expand on the OFDM and may be considered viable candidates for modulation in the future 6G cellular networks.
