11.25-ms-Group-Delay and Low-Complexity Algorithm Design of 18-Band Quasi-ANSI S1.11 1/3 Octave Digital Filterbank for Hearing Aids

 A novel algorithm and architecture design for 18-band quasi-class-2 ANSI S1.11 1/3 octave ?lter bank. The proposed design has several advantages such as lower group delay, lower computational complexity, and lower matching error. The technique we developed in this paper can be summarized as follows: 1) a simple low-pass ?lter (LPF) and discrete cosine transform (DCT) modulation are utilized to generate a uniform 9-band ?lter bank ?rst, and then all elements z-1 of are replaced by all-pass ?lters to obtain a non-uniform ?lter bank; 2) a fast recursive structure and variable-length algorithm is further developed to ef?ciently accomplish DCT modulation. Thus, the spectrum of LPF can be easily spanned and ?exibly extended to the location of the desired central frequency; 3) after employing the multi-rate algorithm, an 18-band non-uniform ?lter bank is generated from two 9-band sub ?lter banks by following the proposed design steps and parameter determinations. Compared with the latest Liu et al.'s quasi-class-2 ANSI S1.11 design, the proposed method-I (Proposed-I) totally has 72.8% reduction for multiplications per sample, 11.25-ms group delay, and 59 additions decreased per sample. Moreover, the maximum matching error of the proposed method-II (Proposed-II) is averagely equal to 1.79 dB much smaller than that of the latest Wei et al.'s design. For the proposed variable-length DCT modulation, only 2 adders, 2 multipliers, 2 multiplexers, and 5 registers are required for hardware implementation after applying VLSI retiming scheme. Overall, the proposed ?lter bank design would be a new solution for future applications in the area of hearing aids.
