ABSTRACT:
A generator generates a composite code from dithered copies of a reference code to form an optimal stationary dither code. The generator either dithers the length of the reference code to generate a boundary dither code composed of a series varying length short codes, or it dithers the phase of the reference code to generate rotation dither code composed of a series of fixed length short codes that vary in phase. The generator dithers the reference code according to a dither pattern. The composite code is an optimal dither code, having an optimal autocorrelation properties, by generating a dither pattern in which phase vectors for the constituent code are not repeated within the code.
