Gray code Design for N-Dimensional Signal Sets Using Genetic Algorithm & Binary Search Techniques
Lian T. Lee, J. Foster · 2005
Gray code design in this paper is based on the characteristic of the successive coded characters never differ in more than one bit. Base on this feature, Gray code can be used to distinguish the number of closest distances of the signals by the values of the Hamming distance of the codewords that encoder assign to the signals. Thus, in this research, two techniques which are genetic algorithm and binary search are used to design this code. The basic properties of both algorithms, the results of both techniques and future work will be discussed.
