Joint 3D Positioning and Network Synchronization in 5G Ultra-Dense Networks Using UKF and EKF
Mike Koivisto, Mário Costa, Aki Hakkarainen +2
It is commonly expected that future fifth generation (5G) networks will be deployed with a high spatial density of access nodes (ANs) in order to meet the envisioned capacity requi…
Covariance-Based OFDM Spectrum Sensing with Sub-Nyquist Samples
Alireza Razavi, Mikko Valkama, Danijela Cabric
In this paper, we propose a feature-based method for spectrum sensing of OFDM signals from sub-Nyquist samples over a single band. We exploit the structure of the covariance matrix…
Impact of Received Signal on Self-interference Channel Estimation and Achievable Rates in In-band Full-duplex Transceivers
Dani Korpi, Lauri Anttila, Mikko Valkama
In this paper we analyze the effect of the calibration period, or lack of, on self-interference channel estimation in the digital domain of in-band full-duplex radio transceivers.…
Feasibility of In-band Full-Duplex Radio Transceivers with Imperfect RF Components: Analysis and Enhanced Cancellation Algorithms
Dani Korpi, Lauri Anttila, Mikko Valkama
In this paper we provide an overview regarding the feasibility of in-band full-duplex transceivers under imperfect RF components. We utilize results and findings from the recent re…
Modeling and Efficient Cancellation of Nonlinear Self-Interference in MIMO Full-Duplex Transceivers
Lauri Anttila, Dani Korpi, Emilio Antonio-Rodríguez +2
This paper addresses the modeling and digital cancellation of self-interference in in-band full-duplex (FD) transceivers with multiple transmit and receive antennas. The self-inter…
Analytic Expressions and Bounds for Special Functions and Applications in Communication Theory
Paschalis C. Sofotasios, Theodoros A. Tsiftsis, Yury A. Brychkov +3
This work is devoted to the derivation of novel analytic expressions and bounds for a family of special functions that are useful in wireless communication theory. These functions…
