Title : Impact of Time and Frequency Misalignments in OFDM based In-band Full-duplex Systems 
Authors : Haesoon Lee, Jaeyoung Choi, Dongkyu Kim, and Daesik Hong 
Conference : IEEE WCNC 2017 
Abstract : When two nodes communicate using in-band fullduplex (FD) with orthogonal frequency division multiplexing (OFDM), the self-interference (SI) and desired signals experience a time and frequency misalignment problem. In this article, we introducetheeffectoftimingandfrequencyoffsetsinFDsystems. A conventional FD node simultaneously receives two signals: the desired signal and the SI. The FD node then synchronizes based on the desired signal, and the SI is distorted by timing and frequency offsets. These timing and frequency offsets break orthogonality and create inter-symbol interference and interchannel interference that degrade the performance of the selfinterference cancellation (SIC). To address this, we design a modified digital SIC approach that considers the timing and frequency offset and synchronizes the desired signal and the SI in consecutive order.
