"Binary phase shaping, contrast ratio, and merit".
We construct and study +1/-1 sequences that mimic randomly produced sequences. The pseudorandomness property discussed here is aperiodic autocorrelation - a random sequence typically has low correlation with truncated versions of itself. Golay's merit factor is a single parameter describing the autocorrelation quality of a sequence. The sequences we discuss are all constructed using the Legendre symbol on finite fields pf prime order. Our interest came from a problem in chemical instrumentation.
