Kazaz, T. (author), Romme, J.P.A. (author), Janssen, G.J.M. (author), van der Veen, A.J. (author)The presence of rich scattering in indoor and urban radio propagation scenarios may cause a high arrival density of multipath components (MPCs). Often the MPCs arrive in clusters at the receiver, where MPCs within one cluster have similar angles and delays. The MPCs arriving within a single cluster are typically unresolvable in the delay domain....conference paper 2021

Kazaz, T. (author), Janssen, G.J.M. (author), van der Veen, A.J. (author)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 multipath components (MPCs) from bandlimited observations of communication signals. It this paper, we consider the problem of multiband channel sampling and TD...conference paper 2020

Kazaz, T. (author), Rajan, R.T. (author), Janssen, G.J.M. (author), van der Veen, A.J. (author)Achieving high resolution time-of-arrival (TOA) estimation in multipath propagation scenarios from bandlimited observations of communication signals is challenging because the multipath channel impulse response (CIR) is not bandlimited. Modeling the CIR as a sparse sequence of Diracs, TOA estimation becomes a problem of parametric spectral...conference paper 2019
