... ρ] 0 otherwise, (8) so that the autocorrelation at a lag, or period, p ∈ Z + for a symbol (or pattern of symbols) is simply the count of the number of instances of that symbol at a spacing of ρ. Consider ... functions, the notion of periodicity in the Fourier sense is described in terms of the frequencies of those basis functions onto which the projections of...
