On Low-Complexity Maximum-Likelihood Decoding of Convolutional Codes
Abstract--This letter considers the average complexity of maximum-likelihood (ML) decoding of convolutional codes. ML decoding can be modeled as finding the most probable path take...

Sequence Families With Low Correlation Derived From Multiplicative and Additive Characters
For integer r satisfying 0 ≤ r ≤ p − 2, a sequence family Ωr of polyphase sequences of prime period p, size (p − 2)pr , and maximum correlation at most 2 + (r + 1) √ p...

Steiner Transitive-Closure Spanners of Low-Dimensional Posets
Given a directed graph G = (V, E) and an integer k ≥ 1, a Steiner k-transitive-closure-spanner (Steiner k-TC-spanner) of G is a directed graph H = (VH , EH ) such that (1) V ⊆ ...
