Beyond Minimum Distance: The Optimal Leading Coefficient in the High-SNR Error-Probability Expansion for AWGN Spherical Codes
Nikola Zlatanov
Packing-optimal spherical codes attain the largest achievable minimum distance and hence the optimal error exponent at high SNR. Among these codebooks held fixed as SNR gro…
Recurrent Transformer-Based Near- and Far-Field THz Wideband Channel Estimation for UM-MIMO
Dmitry Artemasov, Alexander Shmatok, Kirill Andreev +3
The integration of terahertz communications and ultra-massive multiple-input multiple-output (UM-MIMO) systems in 6G networks is motivated by their ability to enable unprecedented…
LO-Free Phase and Amplitude Recovery of an RF Signal with a DC-Stark-Enabled Rydberg Receiver
Vladislav Katkov, Nikola Zlatanov
We present a theoretical framework for recovering the amplitude and carrier phase of a single received RF field with a Rydberg-atom receiver, without injecting an RF local oscillat…
List Estimation
Nikola Zlatanov, Amin Gohari, Farzad Shahrivari +1
Classical estimation outputs a single point estimate of an unknown -dimensional vector from an observation. In this paper, we study \emph{-list estimation}, in which a single…
Hybrid Beamforming via Programmable Unitary RF Networks
Nikola Zlatanov, Damir Salakhov
Conventional hybrid beamforming architectures are often compared with one another and with the fully-digital architecture under the same \emph{radiated} antenna power. However, the…
A Narrowband Fully-Analog Multi-Antenna Transmitter
Nikola Zlatanov
This paper proposes a narrowband fully-analog -antenna transmitter that emulates the functionality of a narrowband fully-digital -antenna transmitter. Specifically, in symbol…
