## CXCOV Circular Cross Covariance function estimates. ...

CXCOV circular Cross Covariance function estimates.

CXCOV(a, b), where a and b are two signals of the same length, both periodic signals and real.

[lags, cc]=CXCOV(a, b) returns the length M-1 circular cross covariance sequence cc with corresponded lags.

where vector b is shifted CIRCULARLY by k samples.

The function doesn't check the format of input vectors a and b!

**The circular cross covariance is the normalized circular cross correlation function of two vectors with their means removed:**

c(k) = sum[a(n)-mean(a))*conj(b(n k)-mean(b))]/[norm(a-mean(a))*norm(b-mean(b))];where vector b is shifted CIRCULARLY by k samples.
