Design of Linear-phase Fir Filters with Minimum Hamming Distance
In this paper a new approach for the design of linear phase FIR filters with discrete coefficients is proposed. A mixed integer linear programming (MILP) problem is formulated that minimizes the total Hamming distance between the adjacent coefficients, i.e., the number of bit switches of the coefficients. The Hamming distance between the coefficients is a good measure of the power consumption, ...
متن کاملDesign of optimum high-order finite-wordlength digital FIR filters with linear phase
A novel iterative quantization procedure for the design of finite wordlength linear phase FIR filters of high order and minimum frequency domain error is proposed: a one by one increased number of filter coefficients is quantized where the augmented frequency domain error is re-minimized in each case. This new approach achieves a smaller frequency domain error than rounding of the optimal non-q...
متن کاملDesign of Finite Word Length Linear-Phase FIR Filters in the Logarithmic Number System Domain
Logarithmic number system (LNS) is an attractive alternative to realize finite-length impulse response filters because of multiplication in the linear domain being only addition in the logarithmic domain. In the literature, linear coefficients are directly replaced by the logarithmic equivalent. In this paper, an approach to directly optimize the finite word length coefficients in the LNS domai...
متن کاملThe design of peak constrained least squares FIR filters with low complexity finite precision coefficients
A method for the design of Peak Constrained Least Squares (PCLS) Finite duration Impulse Response (FIR) digital filters with low complexity Finite Precision Coefficients (FPC) based on Adams’ optimality criterion and an efficient local search is presented. Simple quantization of the infinite precision coefficients typically leads to filter designs which fail to meet the frequency response, Pass...
متن کاملDesign of Non-Uniformly Spaced Linear Phase FIR Filters Using Mixed Integer Linear Programming
In this correspondence, a more efficient algorithm thanthe overlap-and-add (or overlap-and-save) method is deveIoped forquickly computing the convolution involving very long impulse response.By dividing the input and the impulse response into segments ofproper length, the algorithm requires fewer multiplications than theexisting methods and therefore reduces the complexity o...
