Hi,
If E[wwH]=T, where w is a zero-mean row-vector and H is the Hermitian transpose then assuming that H is another random matrix, it holds that
E[H w (H w)H] = T H HH or T E[H HH] ??
In other words, the expectation operation still holds as in the latter expression or vanishes as in the second equality above ??
Thank you in advance.
