Impact of Backward Crosstalk in 2x2 MIMO Transmitters on NMSE and Spectral Efficiency
Peter Händel, Özlem Tuğfe Demir, Emil Björnson +1
We consider backward crosstalk in 2 x 2 transmitters, which is caused by crosstalk from the outputs of the transmitter to the inputs or by the combination of output crosstalk and i…
Clock synchronization over networks using sawtooth models
Pol del Aguila Pla, Lissy Pellaco, Satyam Dwivedi +2
Clock synchronization and ranging over a wireless network with low communication overhead is a challenging goal with tremendous impact. In this paper, we study the use of time-to-d…
Clock synchronization over networks -- Identifiability of the sawtooth model
Pol del Aguila Pla, Lissy Pellaco, Satyam Dwivedi +2
In this paper, we analyze the two-node joint clock synchronization and ranging problem. We focus on the case of nodes that employ time-to-digital converters to determine the range…
Multi-kernel Regression For Graph Signal Processing
Arun Venkitaraman, Saikat Chatterjee, Peter Händel
We develop a multi-kernel based regression method for graph signal processing where the target signal is assumed to be smooth over a graph. In multi-kernel regression, an effective…
CLIMEX: A Wireless Physical Layer Security Protocol Based on Clocked Impulse Exchanges
Satyam Dwivedi, John Olof Nilsson, Panos Papadimitratos +1
A novel method and protocol establishing common secrecy based on physical parameters between two users is proposed. The four physical parameters of users are their clock frequencie…
Predicting Graph Signals using Kernel Regression where the Input Signal is Agnostic to a Graph
Arun Venkitaraman, Saikat Chatterjee, Peter Händel
We propose a kernel regression method to predict a target signal lying over a graph when an input observation is given. The input and the output could be two different physical qua…
