Joint blind calibration and time-delay estimation for multiband ranging
Tarik Kazaz, Mario Coutino, Gerard J. M. Janssen +1
In this paper, we focus on the problem of blind joint calibration of multiband transceivers and time-delay (TD) estimation of multipath channels. We show that this problem can be f…
Time Delay Estimation from Multiband Radio Channel Samples in Nonuniform Noise
Tarik Kazaz, Gerard J. M. Janssen, Alle-Jan van der Veen
The multipath radio channel is considered to have a non-bandlimited channel impulse response. Therefore, it is challenging to achieve high resolution time-delay (TD) estimation of…
Multiresolution time-of-arrival estimation from multiband radio channel measurements
Tarik Kazaz, Raj Thilak Rajan, Gerard J. M. Janssen +1
Achieving high resolution time-of-arrival (TOA) estimation in multipath propagation scenarios from bandlimited observations of communication signals is challenging because the mult…
Joint Ranging and Clock Synchronization for Dense Heterogeneous IoT Networks
Tarik Kazaz, Mario Coutino, Gerard J. M. Janssen +2
Synchronization and ranging in internet of things (IoT) networks are challenging due to the narrowband nature of signals used for communication between IoT nodes. Recently, several…
Efficient Calibration of Radio Interferometers Using Block LDU Decomposition
Ahmad Mouri Sardarabadi, Alle-Jan van der Veen, Léon V. E. Koopmans
Having an accurate calibration method is crucial for any scientific research done by a radio telescope. The next generation radio telescopes such as the Square Kilometre Array (SKA…
Sparsity-Exploiting Anchor Placement for Localization in Sensor Networks
Sundeep Prabhakar Chepuri, Geert Leus, Alle-Jan van der Veen
We consider the anchor placement problem in localization based on one-way ranging, in which either the sensor or the anchors send the ranging signals. The number of anchors deploye…
