Ternary Constant Weight Codes
Let A3(n, d, w) denote the maximum cardinality of a ternary code with length n, minimum distance d, and constant Hamming weight w. Methods for proving upper and lower bounds on A3...

On Perfect Ternary Constant Weight Codes
We consider the space of ternary words of length n and fixed weight w with the usual Hamming distance. A sequence of perfect single error correcting codes in this space is construc...

A Weighted Coding in a Genetic Algorithm for the Degree-Constrained Minimum Spanning Tree Problem
The coding by which chromosomes represent candidate solutions is a fundamental design choice in a genetic algorithm. This paper describes a novel coding of spanning trees in a gen...

Performance of Space-Time Codes: Gallager Bounds and Weight Enumeration
Since the standard union bound for space-time codes may diverge in quasi-static fading channels, the limit-before-average technique has been exploited to derive tight performance b...

Small weight codewords in LDPC codes defined by (dual) classical generalized quadrangles
We find lower bounds on the minimum distance and characterize codewords of small weight in low-density parity check codes defined by (dual) classical generalized quadrangles. We a...
