Help on MMSE and Least Squares

Started by A_S November 25, 2006
Hi,
I'm a rookie in Adaptive DSP and equalization and I have questions bugging
me and I need some help from you all.Now wherever I have read,they talk of
MMSE criterion and a LS(Least Square)Solution/Fit.From how I see, MMSE is
point on error surface in terms of expectation of error and a LS is best
solution with limited degrees of freedom.Can anyone throw a little more
light on how these are related along with their relation to ergodicity and
staionarity?

Thanks a lot,
AS
