Abstract

Almost all nonbinary codes were designed for the Hamming metric. The Lee metric was defined by Lee in 1958. Golomb and Welch (1968) and Berlekamp, 1968a, Berlekamp, 1968b have designed codes for the Lee metric. In this paper, we derive all the discrete, memoryless, symmetric channels matched to the Lee metric, and investigate general properties of Lee metric block codes. Finally, a class of cyclic Lee metric codes is defined and the number of information symbols is discussed.
