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…
Programmable Unitary RF Networks for Narrowband Hybrid Beamforming
Nikola Zlatanov, Damir Salakhov
Conventional hybrid beamforming architectures are compared with one another and with the fully-digital architecture under the same radiated antenna power. However, the physically r…
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…
An Incentive-Compatible Reward Sharing Mechanism for Mitigating Mirroring Attacks in Decentralized Data-Feed Systems
Sina Aeeneh, Nikola Zlatanov, Jiangshan Yu
Decentralized data-feed systems enable blockchain-based smart contracts to access off-chain information by aggregating values from multiple oracles. To improve accuracy, these syst…
A Method For Bounding Tail Probabilities
Nikola Zlatanov
We present a method for upper and lower bounding the right and the left tail probabilities of continuous random variables (RVs). For the right tail probability of RV with proba…
HoloBeam: Learning Optimal Beamforming in Far-Field Holographic Metasurface Transceivers
Debamita Ghosh, Manjesh Kumar Hanawal, Nikola Zlatanova
Holographic Metasurface Transceivers (HMTs) are emerging as cost-effective substitutes to large antenna arrays for beamforming in Millimeter and TeraHertz wave communication. Howev…
A New Type Of Upper And Lower Bounds On Right-Tail Probabilities Of Continuous Random Variables
Nikola Zlatanov
In this paper, I present a completely new type of upper and lower bounds on the right-tail probabilities of continuous random variables with unbounded support and with semi-bounded…
New Bounds on the Accuracy of Majority Voting for Multi-Class Classification
Sina Aeeneh, Nikola Zlatanov, Jiangshan Yu
Majority voting is a simple mathematical function that returns the value that appears most often in a set. As a popular decision fusion technique, the majority voting function (MVF…
