a valid inner product for the space of finite-energy functions defined over [0,T]?
Consider subspace of L2(0,T) that consists of signals of the form
where Xn may be complex valued.
where xn are known and Nn are zero mean, iid Gaussian noise samples with variance σ2. The parameters a and b are to be determined. We can think of the solution to this problem as the projection of onto the subspace spanned by a + b
denotes a vector of 1’s. Explain why or why not?
