| Abstract | (in Japanese) | (See Japanese page) |
| (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-invariantMDTWTs 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. |
