Optimal design of multiplierless FIR filter
Jie Fang, Ting Yi, Hong Zhiliang · 2003
A new structure proposed in this paper, which synthesizes a half-band filter by multiple use of the subfilters saves the hardware cost greatly. Then the coefficient optimization based on simulated annealing algorithms is developed and it obtains better the frequency response performance of the filter than the coefficient optimization based on greedy algorithms, such as local search.
