摘要：
The canonic signed digit code used to represent the coefficients of power-of two FIR (2PFIR) filter is nonuniformly distributed in the coefficient space. This paper proposed a neighboring full-search algorithm to design the multiplierless FIR filter such that this nonuniform distribution characteristics is exploited. The proposed procedure can provide a multiplierless FIR filter with fewer numbers of nonzero digits compared with others due to the joint; consideration in finding and quantizing the FIR filter coefficients and the exhaustive search nature of the proposed algorithm.
