Optical Pulse Coding for Maximum Data Rate
Abstract
This study shows the benefit of a two stage hierarchy of coding schemes for achieving maximum data rate transmission in optical fiber communications. A first matched filter identifies the code/microchannel orthogonal code and a second matched filter identifies the data either BPSQ'd or pulse position modulated with error correction. The novel achievements of this study are: (1) the introduction of group theory (Young frame and tableaux methods) in characterizing code properties for optimum code design with optimum auto and cross correlation properties; (2) the development of Lexicographic Greedy code algorithms for perfect codes and orthogonal codes; (3) the demonstration of orthogonal codes as extended Reed Solomon codes and their implementation; (4) the implementation of Zech logarithmic code constructions; (5) the application of optical Fourier methods implementing matched filters in optical hub systems; (6) the analysis of code properties in terms of underlying group symmetry structure; (7) the confirmation of the utility of shepherding pulse techniques in bit parallel wavelength division multiplexing (BPWD) for maintaining pulse alignment; and (8) bit error analysis; all addressed in order to achieve the goal of the maximum in high data rate optical fiber communications commensurate with available device technology.
