Abstract

Results from design, synthesis, and analysis of optimal mutually dispersive symbols are presented as an improvement over existing symbol sets employed in non-linear ambiguity suppression (NLAS). A recently proposed theorem formulates the existence of symbol families having optimal mutual dispersion, a highly desirable property for NLAS applications. Results from theorem analysis are presented and compared to other suitable NLAS symbol sets, showing significant improvement in mutual dispersion characteristics. NLAS ambiguity suppression effectiveness is demonstrated using a set of optimal mutually dispersive symbols.
