Lattice infinite impulse response digital filter with high robustness
摘要
Abstract
A novel lattice filter structure is derived for infinite impulse response(IIR) digital filters with low complexity and high robustness against finite-word-length effects. For an N-th order filter, there are 2N nodes for the input signals to select to minimize the signal power ratio. The new structure using the one-multiplier elementary lattice possesses only (2N + 1) multipliers. Compared with traditional lattice structures in simulation, the proposed structure not only has fewer multipliers, but also yields much smaller signal power ratio.关键词
