recommendations! Published in 2020 at "Multidimensional Systems and Signal Processing"

DOI: 10.1007/s11045-019-00668-1

Abstract: In this paper, we consider circular array design in the presence of a far-field or a near-field signal source. The location of the source is introduced to our optimization problem by its probability density function… read more here.

DOI: 10.1016/j.jsv.2018.11.005

Abstract: Abstract This paper presents a beamforming array design method that uses a large array of microphones and systematically reduces it to a predetermined number of microphones. The microphone, while included in the array, that results… read more here.

DOI: 10.1093/gji/ggy523

Abstract: The design of an optimal array configuration is an important task in array seismology during experiment planning. Theoretically, the array response function (ARF), which depends on the relative position of array stations and frequency content… read more here.

DOI: 10.1109/lcomm.2023.3257739

Abstract: The problem of sparse array design for dual-function radar-communications is investigated. Our goal is to design a sparse array which can simultaneously shape desired beam responses and serve multiple downlink users with the required signal-to-interference-plus-noise… read more here.

recommendations! Published in 2019 at "IEEE Transactions on Information Theory"

DOI: 10.1109/tit.2018.2873795

Abstract: We consider the problem of far-field sensing by means of a sensor array. Traditional array geometry design techniques are agnostic to prior information about the far-field scene. However, in many applications such priors are available… read more here.

DOI: 10.1109/tsp.2025.3619150

Abstract: In this paper, we focus on the problem of joint waveform and array design for direction-of-arrival (DOA) estimation using self-organized unmanned aerial vehicle (UAV) swarm. Exploiting the Cramér-Rao lower bound (CRLB) as the performance metric,… read more here.
