I am looking for a program which calculates cross correlation and auto
correlation any help please?

A "program" of what kind? There is Matlab and its clones, Scilab and GNU Octave that will do it rather readily. There must also be math routines in your favorite language if that's what you mean. I think Intel's math library is the most reasonably priced and likely to be pretty good for their processors. The only difference between cross and auto is the inputs..... You can substitute correlation by using convolution - just reverse one of the inputs. So, look for correlation programs also if that manipulation is within your scope. Fred
And, depending on the degree of correlation that you
wish to do, the Fourier Series and Transform are a
means of correlating your input signal against the
domain of cisoidal signals.

Thanks for the response I was thinking of a matlab program for
calculating cross correlation in a code used in Optical code division
