....[15] that the polyphase transfer matrix of a paraunitary cosine modulated filter bank is a parallel bank of power complementary, two channel filter bank cascaded by the modulation matrix , as Shown in Fig. 3(a) 15] Fig. 3(b) shows the lattice structure for the two channel lossless lattice [15] [29]. Since the filter bank considered in this paper is a general case of the one presented in [15] there must be a lattice structure for the case where the length is arbitrary. Section IV will elaborate on this lattice structure. IV. LATTICE STRUCTURES FOR ARBITRARY LENGTH COSINE MODULATED FILTER ....

....cosine modulated filter bank with prototype length N 2ram is given. This structure is based on the two channel lossless lattice (shown in Fig. 3(b) H o(Z) H 1 (z) HM. 1 (z) COg 0 0 Fig, 3, a) Lti structure of the cosinmodulated filter bk; b) two chnel lossless lattice, introduced in [29], which ensures the power complementary (PC) property between pairs of polyphase components. For the case considered in [15] all pairs of polyphase components have the same length and fall under mode a, as mentioned earlier. In this section, it is shown that each of the different modes can be ....
