Noise Issue

What is the meaning of correlated noise and uncorrelated noise?Anyone here can explained in details?

It is the relationship between two unwanted signals. If they are from different sources they are usually uncorrelated. That means that if you multiply them together there will be no DC term produced. If they are from the same basic source like a clocked system they will have parts in common and multiplying them together will produce a DC component.

Is there any good website for more details explanations?

hope this tutorial helps u.. just did a google search and found its good! there are also many other books which explains very good!

and, correlation as the term implies denotes the relation between any two entities. if they are signals, relation between the two signals, incase of a noise signal, they indicate the relation between two noise signals. in general two noise signals are taken to be uncorelated for calculation purposes, unless or otherwise they are absolutely necessary. You could go for more info from any signals and systems book....
