Abstract :
A new fast multichannel QR decomposition (QRD) least squares (LS) adaptive algorithm is presented in this paper. The algorithm deals with the general case of channels with different number of delay elements and is based exclusively on numerically robust orthogonal Givens rotations. The new scheme processes each channel separately and as a result it comprises scalar operations only. Moreover, the proposed algorithm is implementable on a very regular systolic architecture and offers substantially reduced computational complexity compared to previously derived multichannel fast QRD schemes.
