A least squares approach to blind beamforming
M. Wax, Y. Anu · IEEE Transactions on Signal Processing · 1999
We present a least squares approach to blind beamforming. Two estimation criteria are derived. One turns out to coincide with the Comon (1990, 1994) criterion, whereas the other is a computationally simpler criterion similar in nature to the joint approximate diagonalization of eigenmatrices (JADE) criterion.
