Abstract:
1. A method for determining with a processor of a correlation value between a first sequence of n-state symbols and a second sequence of n-state symbols, an n-state symbol having one of n states with n an integer and n>2, the n-state symbol being represented by a signal, comprising: providing the processor with the first sequence of n-state symbols, wherein the first sequence has at least three n-state symbols each with a different one of the n states; adding by the processor of a first value to a sum whenever an n-state symbol in the first sequence is identical to a corresponding symbol in the second sequence which has at least three n-state symbols each with a different one of the n states; and generating by the processor of a signal representing the correlation value when all signals representing the n-state symbols of the first sequence have been processed to determine the sum.
