Analog Error Correcting Codes with Constant Redundancy
Wentu Song, Kui Cai
We consider analog error-correcting codes (analog ECCs) that are designed to correct/detect outlying errors arising in analog implementations of vector-matrix multiplication. The e…

On the Sequence Reconstruction Problem for the Single-Deletion Two-Substitution Channel
Wentu Song, Kui Cai, Tony Q. S. Quek
The Levenshtein sequence reconstruction problem studies the reconstruction of a transmitted sequence from multiple erroneous copies of it. A fundamental question in this field is t…

Sequence Reconstruction for the Single-Deletion Single-Substitution Channel
Wentu Song, Kui Cai, Tony Q. S. Quek
The central problem in sequence reconstruction is to find the minimum number of distinct channel outputs required to uniquely reconstruct the transmitted sequence. According to Lev…
