Abstract :
A method for constructing Lee metric codes over arbitrary alphabet sizes using the elementary concepts of module theory is presented. The codes possess a high degree of symmetry. Codes with two information symbols over arbitrary alphabet sizes are cyclic reversible. For alphabet sizes which are a power of two or an odd prime number, codes with one information symbol are reversible and equidistant, and codes having more than two information symbols are quasi-cyclic reversible. Binary Reed-Muller codes arise as subcodes of the codes presented. A method of constructing equidistant Lee metric codes analogous to maximum length shift register codes is presented.
