Self-Interference in LTE-Advanced and 5G NR Transceivers

Description

The upgrade from 3GPP Long Term Evolution (LTE) towards LTE-Advanced introduced Carrier-Aggregation (CA), necessitating multiple receivers (RX) and transmitters (TX) operating concurrently on a single transceiver die, causing potential interference among them. The introduction of 5G New Radio (5G NR) will require Dual Connectivity (DC) with LTE in the first phase and thus also require a multitude of parallel-operating high-performance receive and transmit chains in a multi-mode LTE-A/5G NR transceiver, driving the need for analog and digital techniques for self-interference mitigation due to coupling between different parts of the transceiver. This paper catalogs the various cross-talk effects and presents digital as well as mixed-signal interference mitigation techniques in condensed form.
