Abstract:
1. A method of processing a signal, wherein the signal is a Zadoff-Chu sequence in which the signal, x, at each position, n, of each root, μ, of the Zadoff-Chu sequence is given by where N ZC is the length of the Zadoff-Chu sequence, the method being a recursive method for determining a plurality of frequency components of the signal, comprising: determining a first frequency component of the plurality of frequency components; determining a component factor by accessing a factor table for use in determining a second frequency component of the plurality of frequency components; determining the second frequency component using the determined first frequency component and the determined component factor; setting an increment variable, γ; and setting an index variable I, wherein said step of determining a component factor comprises loading the component factor from the factor table using the index variable I, the method further comprising: incrementing the index variable I by the increment variable γ for determining a subsequent component factor by loading the subsequent component factor from the factor table using the incremented index variable.
