Uses fft to calculate the circular cross correlation of two periodic signal vectors.This is equivalent to xc(k)=sum(u1.*circshift(u2,k)), but much faster (on the order of 500 times faster for a 1024 point signal).The package also includes two examples. One checks the calculation against the definition. The second compares the speed of the fast algorithm to one based on the definition for a range of input vector sizes.

Requirements: No special requirements
Platforms: Matlab
Keyword: Algorithm Based Calculation Checks Compares Correlation Definition Examples Includes Input Package Periodic Range Signal Sizes Speed Vector Vectorsthis
