Covering in Hamming and Grassmann Spaces: New Bounds and Reed--Solomon-Based Constructions
Samin Riasat, Hessam Mahdavifar
We study covering problems in Hamming and Grassmann spaces through a unified coding-theoretic and information-theoretic framework. Viewing covering as a form of quantization in gen…
Efficient Covering Using Reed--Solomon Codes
Samin Riasat, Hessam Mahdavifar
We propose an efficient algorithm to find a Reed-Solomon (RS) codeword at a distance within the covering radius of the code from any point in its ambient Hamming space. To the best…
Precoding Design for Limited-Feedback MIMO Systems via Character-Polynomial Codes
Siva Aditya Gooty, Samin Riasat, Hessam Mahdavifar +1
This paper presents a precoding codebook design for limited-feedback multiple-input multiple-output (MIMO) systems under the equal-gain transmission (EGT) constraint. In particular…
Decoding Analog Subspace Codes: Algorithms for Character-Polynomial Codes
Samin Riasat, Hessam Mahdavifar
We propose efficient minimum-distance decoding and list-decoding algorithms for a certain class of analog subspace codes, referred to as character-polynomial (CP) codes, recently i…
Quotients of Palindromic and Antipalindromic Numbers
James Haoyu Bai, Joseph Meleshko, Samin Riasat +1
A natural number N is said to be palindromic if its binary representation reads the same forwards and backwards. In this paper we study the quotients of two palindromic numbers and…
New Bounds on Antipowers in Words
Lukas Fleischer, Samin Riasat, Jeffrey Shallit
Fici et al. defined a word to be a k-power if it is the concatenation of k consecutive identical blocks, and an r-antipower if it is the concatenation of r pairwise distinct blocks…
More Infinite Products: Thue-Morse and the Gamma function
Jean-Paul Allouche, Samin Riasat, Jeffrey Shallit
Letting denote the Thue-Morse sequence with values , we note that the Woods-Robbins product $$ \prod_{n \geq 0} \left(\frac{2n+1}{2n+2}\right)^{(-1)^{t_n}} = 2^{-1/2}…
Infinite products involving binary digit sums
Samin Riasat
Let denote the Thue-Morse sequence with values . The Woods-Robbins identity below and several of its generalisations are well-known in the literature \begin…
