Suppose that parameter A, which is a DC level in WGN, is to be estimated; x[n] = A + w[n], n = 0,1, ...,N – 1 Let's observe. Let w[n] be WGN with a mean of zero and variance o^2=1 for all observations. Consider the following estimator: The logical explanation for this estimator is that for a sufficiently high SNR or we do not need to reduce the effect of noise by averaging, thus reducing the computational load. Evaluate whether this approach is valid or not
