...(12) can be simplified as: Z ( UnΛnUHn ) ZH = σ2nI (12) Solving the above formula and getting the whitening matrix is: Z = ( σ2n )1/2 Λ−1/2n UHn (13) So the whitened covariance matrix can be described as: ˜̄R = Ā [ RsA T A∗Rs RsA HA∗Rs RsA T ARs RsA HARs ] ĀH + ZR̄nZH (14) Combined with the MVDR algorithm, the optimal weight can be obtained by: ˜̄wopt = ˜̄R−1ā (θ0) āH (θ0) ˜̄R−1ā (θ0) (15) where ā (θ0) is an extended steering vector of the desired direction....
