Abstract

One of the steps for suppressing the selfinterference (SI) in Full-duplex (FD) communication is digital SI cancellation (DSIC). In orthogonal frequency division multiplexing (OFDM) based FD systems, despite providing significant SI cancellation, the residual SI after DSIC produces significantly high amount of periodic ripples at the transitions between two OFDM symbols. These ripples coincide with the data region of the desired signal when the propagation delay increases between two communicating nodes. In this work, digital SI cancellation performance of the previously proposed ripple reduction solution is evaluated for different communication schemes, considering various DSIC techniques over different modulation types and coding rates.
