This paper studies two families of codes over Z4, MacDonald codes of type α and type β. The torsion code, weight distribution, and Gray image properties are studied. Some intere...
Abstract. Quaternary Z RM (r,m) codes were defined to study the Z4-linearity of ReedMuller codes. In the literature two different definitions of such codes can be found, denoted Z ...
We construct a large number of record-breaking binary, ternary and quaternary codes. Our methods involve the study of BCH-codes over larger fields, concatenation, construction X a...
We show the advantage of Quarternary Decision Diagrams (QDDs) in representing and evaluating logic functions. That is, we show how QDDs are used to implement QDD machines, which y...
