Abstract
A method and apparatus for providing maximum rate modulation or compression encoding and decoding for use with magnetic and optical recording and optical fiber communications is disclosed in which primarily two algorithms are utilized which satisfy the conditions that encoding and decoding require only a small constant number of elementary operations, without multiplications or divisions and that only a small amount of memory space for a small number of integers is required. Thus, the present invention operates with only linear time complexity and only linear memory complexity. The invention utilizes a direct enumeration algorithm to accomplish a mapping and an inverse enumeration algorithm to accomplish an inverse mapping back to enumeration.
