Filter Design for Self-Interference Cancellation

2020
Mitigation of self-interference is the prime challenge in making full-duplex technology feasible in wireless communications. In this chapter, we first present system model of a wireless communication link including a source, full-duplex transceiver, and destination, and discuss different approaches and assumptions when building the signal model.

Joint Equalization and Self-Interference Cancellation for Underwater Acoustic In-Band Full-Duplex Communication

IEEE Journal of Oceanic Engineering
In-band full-duplex (IBFD) communication in underwater acoustic channels is challenged by strong and time-varying self-interference (SI). To detect data symbols, the receiver needs to suppress the SI and equalize the resultant signal to compensate for ...

Photonic Approach for Unambiguous Measurement of AOA and DFS With Self-Interference Cancellation

IEEE Photonics Technology Letters, 2023
We propose a compact photonic system based on a dual-polarization dual-drive Mach–Zehnder modulator (DP-DDMZM) to measure Doppler-frequency-shift (DFS) and angle-of-arrival (AOA).

Self-interference cancellation for full-duplex MIMO transceivers

2015 IEEE Wireless Communications and Networking Conference (WCNC), 2015
Full-duplex operation requires effective self-interference (SI) cancellation that in turn needs reliable SI channel estimation. In this paper, we develop two estimation algorithms suitable for a 2-stage SI cancellation structure. By exploiting the sparsity of the SI channel, we first derive a compressed sensing-based SI channel estimation algorithm to ...

Filter-Less Photonic RF Image-Reject Mixing With Simultaneous Self-Interference Cancellation and Fiber Transmission

Journal of Lightwave Technology, 2022
A filter-free photonic method to simultaneously realize radio frequency (RF) image-reject mixing, self-interference cancellation (SIC), and fiber transmission for in-band full-duplex (IBFD) radio-over-fiber (RoF) link is reported.

Maximum Likelihood Self-Interference Cancellation

2017
In this chapter, we propose a maximum likelihood (ML) approach to jointly estimate the self-interference and the intended channels. We perfectly exploit the known transmitted symbols from its own transceiver and both the known pilot and unknown data symbols from the other intended transceiver.

RIS-Based Self-Interference Cancellation for Full-Duplex Broadband Transmission

IEEE Transactions on Wireless Communications
Full-duplex (FD) is an attractive technology that can significantly boost the throughput of wireless communications. However, it is limited by the severe self-interference (SI) from the transmitter to the local receiver.
