Abstract
The fast implementation algorithm of M-band orthogonal wavelet filter bank (OWFB) with length L equal to 2M is proposed by using the lossless matrix factorisation method. The computational complexity of the proposed algorithm becomes lower than that of the direct filtering method (DFM):(M2+M+1) multiplications and M2+2M-1) additions against 2M2 and (2M2-M), respectively
