In this study, a novel iterative turbo digital self interference cancellation (DSIC) algorithm is proposed to eliminate remaining self interference (SI) signal, which is contaminated by signal of interest (SoI), subject to time varying SI channel. SoI creates a noise floor for the estimation of SI signal; hence, estimation accuracy significantly degrades. In order to improve the estimation accuracy, it is proposed that for each block, SoI is decoded via signal decomposition based on generalized memory polynomial (GMP) and neural network (NN) nonlinear regressors and its copy subtracted from received signal iteratively so that SoI contamination is decreased. This procedure is performed in an online manner during data transmission stage; therefore, it does not yield extra training overhead. In addition, since each block is processed independently, the proposed algorithm can track varying channel efficiently. Both numerical results and hardware implementations are presented to demonstrate the effectiveness of the proposed algorithm.

An Adaptive-Iterative Nonlinear Interference Cancellation in Time-Varying Full-Duplex Channels Kurt, Anıl; Salman, Murat Babek; Saraç, Uğur Berkay; Güvensen, Gökhan Muzaffer (2022-01-01) In this paper, first, the sensitivity of traditional Full-Duplex (FD) communication systems to time variation in the self-interference (SI) channel is demonstrated via performance analysis. It is seen that conventional schemes are not capable of providing efficient operation regarding practical concerns such as spectral efficiency, SI channel aging and learning accuracy, and the contamination of signal-of-interest (SoI). Then, in regard to the aforementioned concerns, a practical FD operation together with ...
Diversity-Multiplexing Tradeoff for the Multiple-Antenna Wire-tap Channel Yüksel Turgut, Ayşe Melda; Erkip, Elza (2011-03-01) In this paper the fading multiple antenna (MIMO) wire-tap channel is investigated under short term power constraints. The secret diversity gain and the secret multiplexing gain are defined. Using these definitions, the secret diversity-multiplexing tradeoff (DMT) is calculated analytically for no transmitter side channel state information (CSI) and for full CSI. When there is no CSI at the transmitter, under the assumption of Gaussian codebooks, it is shown that the eavesdropper steals both transmitter and ...
An experimental and theoretical study on the utilization of observation channel for transmitter noise cancellation in in-band full-duplex radios Kaya, Altuğ; Güvensen, Gökhan Muzaffer; Department of Electrical and Electronics Engineering (2022-8-31) Conventional Half-Duplex (HD) systems orthogonalize transmitted and received signals either in time, frequency or both in order not to interfere a signal-of-interest with a transmitted signal. If this interference (also known as self-interference, SI) can be suppressed, a radio can perform simultaneous transmission and reception in the same time & frequency resource and, hence, known as In-Band Full-Duplex (IBFD). IBFD systems potentially double the spectral efficiency compared to their HD counterparts as l...
An Automatically Mode-Matched MEMS Gyroscope With Wide and Tunable Bandwidth Sonmezoglu, Soner; Alper, Said Emre; Akın, Tayfun (Institute of Electrical and Electronics Engineers (IEEE), 2014-04-01) This paper presents the architecture and experimental verification of the automatic mode-matching system that uses the phase relationship between the residual quadrature and drive signals in a gyroscope to achieve and maintain matched resonance mode frequencies. The system also allows adjusting the system bandwidth with the aid of the proportional-integral controller parameters of the sense-mode force-feedback controller, independently from the mechanical sensor bandwidth. This paper experimentally examines...
An Efficient Hybrid Beamforming and Channel Acquisition for Wideband mm-Wave Massive MIMO Channels Kurt, Anıl; Güvensen, Gökhan Muzaffer (2019-01-01) In this paper, an efficient hybrid beamforming architecture together with a novel spatio-temporal receiver processing is proposed for single-carrier (SC) mm-wave wideband massive MIMO channels in time-domain duplex (TDD) mode. The design of two-stage beamformers is realized by using a virtual sectorization via second-order channel statistics based user grouping. The novel feature of the proposed architecture is that the effect of both inter-group-interference (due to non-orthogonality of virtual angular sec...
