Abstract(in English) | In this paper, we show novel characteristics of even-stacked cosine-modulated filter banks (ECFBs) which have been proposed by Lin and Vaidyanathan. It is well-known that ECFBs can save their design cost and guarantee the linear phase property. In addition to these attractive features, we add three unknown features. First, ECFBs can be regarded as M-band dual-tree wavelet transform (MDTWT) which has proposed recently. Second, ECFBs have rich directional selectivity. Third, ECFBs with oversampling ratio of 2 provide shift-invariant MDTWTs which assure the shift-invariance at any decomposition levels. Therefore, ECFBs can provide an efficient design method for the MDTWT with linear phase, rich directional selectivity, and shift-invariance. In this paper, we verify these facts by theoretical analysis and simulations. |
