Hi,
as I am new in Matlab, so I need your help. I want to replace the following inverse matrix (X'*X)^1 with its expectation value: E{(X'*X)^1} = E{1/Xk^2}I X'*X and (X'*X)^1 is a diagonal matrix. Could anyone give me an Idea how to write it in matlab this expectation value. The elements of a matrix X are composed by QPSK symbols, or 16QAM, or 64QAM. Assume for now QPSK. Assuming the same signal constellation on all tones and equal probability on all constellation points. Thanks in advande.
