Design of High-Resolution Cosine-Modulated Transmultiplexers with Sharp Transition Band

Two-Rate Based Structures for Computationally Efficient Wide- Band FIR Systems

“…Specifically, by realizing F(z) as an FRM filter, see [3][4][5][6][7][8][9][10], we can express the transfer function as…”

“…For frequency-selective wide-band FIR filters, the frequency-response masking (FRM) technique can be employed for complexity reductions due to its use of sparse (namely periodic) subfilters, see [3][4][5][6][7][8][9][10]. For other functions, the FRM technique cannot be used directly, and one therefore has to seek other methods to reduce the complexity.…”

Reconfigurable Multirate Systems in Cognitive Radios

“…and a 3-dB cutoff frequency at ωT = π 2M as discussed in Diniz et al (2004); Martin-Martin et al (2005). If 0 < ρ≤1, only the adjacent branches overlap.…”

Design of Linear-Phase Filter Banks with Multiplier-Less Lattice Structures

“…Unlike traditional methods with fixed filter structures, the structures were simultaneously designed and optimized in a dynamic fashion. A class of 2-channel quadrature mirror filters was investigated in [27] and the design of filter banks with sharp transition band was reported in [28] [29]. In [30], the design of multiplier-less decimation filters based on an extended search of cyclotomic polynomials (CP) was proposed.…”
