Original Kurzfassung:
This brief deals with self-interference (SI) effects in mobile communication radio frequency (RF) transceivers. The basics of current communication standards, namely Long-Term Evolution (LTE) and 5G, are outlined with a focus on carrier aggregation (CA). RF transceivers that support frequency-division duplex (FDD) and CA variants operate multiple receivers and transmitters simultaneously. We illustrate the resulting SI problems, present suitable models for different SI categories and discuss the associated interference estimation tasks. Moreover, we explain the basic architecture of two common countermeasures: digital and mixed-signal SI cancellation.
