| Abstract: | Coherent codes (arrays of 1 and -1 whose aperiodic autocorrelation approximateds the delta function) are of interest for several imaging applications. Analytic techniques of code generation have not had much impact on this class of codes. In practice, useful codes are found by hill-climbing searches accomplishing either code generation or improvement. One such improvement algorithm is described. |
