Chi-Squared Geometry for Robust Finite-Blocklength Information and Dispersion Analysis
Hassan Tavakoli, Thinh Nguyen, Bella Bose
We develop a column-wise chi-squared geometry for discrete memoryless channels (DMCs) yielding tight, logarithm-free bounds on mutual information, channel dispersion, and finite-bl…
Combinatorial Capacity Bounds for the -ary Deletion Channel
Hassan Tavakoli, Thinh Nguyen, Bella Bose
We study the \(q\)-ary deletion channel via the pattern-count scalar \(N_n(x,y)\), the number of deletion subsets mapping \(x\inΣ_q^n\) to \(y\inΣ_q^k\), which factorizes the trans…
Guesswork Under Linear Constraints: Exact Exponent for Coset Decoding
Hassan Tavakoli
We establish the exact exponential growth rate of the -th moment of the constrained guesswork -- the rank of the true noise vector within its syndrome coset…
RankGuardPolar Private Public Finite Length Polar Codes with Rank-Certified Leakage
Hassan Tavakoli, Thinh Nguyen, Bella Bose
We introduce \textbf{RankGuard-Polar}, a framework for safely publishing a subset of polar codeword coordinates over shared public resources. We assume a strong eavesdropper who ha…
Parameter Estimation of Mutual Information Maximized Channels
Hassan Tavakoli, Thinh Nguyen, Bella Bose
We study the problem of estimating a parametric discrete memoryless channel \( p(y \mid x; \boldsymbolθ) \) when the transmitter selects its input distribution \( π\) to maximize m…
Optimal Rate Irregular LDPC Codes in Binary Erasure Channel
H. Tavakoli, M. Ahmadian, M. Reza Peyghami
In this paper, we design the optimal rate capacity approaching irregular Low-Density Parity-Check code ensemble over Binary Erasure Channel, by using practical Semi-Definite Progra…
