Digitally-assisted photonic analog domain self-interference cancellation for in-band full-duplex MIMO systems via LS algorithm with adaptive order

no code implementations3 Aug 2022 Moxuan Han, Yang Chen

The SIC and frequency downconversion are achieved in the optical domain via a dual-parallel Mach-Zehnder modulator (DP-MZM), while the downconverted signal is processed by the LS algorithm with adaptive order that is used to track the response of the multipath self-interference (SI) channel and reconstruct the reference signal for SIC.

Digital-assisted photonic analog wideband multipath self-interference cancellation

no code implementations12 Nov 2021 Moxuan Han, Taixia Shi, Yang Chen

The proposed method can solve the performance limitation in the previously reported SIC methods of constructing the multipath SI signal using a single reference caused by the limited dynamic range of the digital-to-analog converter when the direct-path SI signal is much stronger than the sub-weak reflection-path SI signals.

Photonics-assisted wideband RF self-interference cancellation with digital domain amplitude and delay pre-matching

no code implementations7 Sep 2021 Taixia Shi, Moxuan Han, Yang Chen

One dual-drive Mach-Zehnder modulator is used to implement the analog self-interference cancellation by pre-adjusting the delay and amplitude of the reference signal applied to the dual-drive Mach-Zehnder modulator in the digital domain.
