多目标满意优化在数字滤波器设计中的应用

Application of multicriterion satisfactory optimization in FIR digital filter design

提出了一种应用多目标满意优化进行数字滤波器优化设计的方法。给出了计算模型和算法。该方法以满意度函数反映设计者对性能指标的评价,更符合实际要求。应用该方法对有限冲击响应数字滤波器的过渡带采样点的取值进行优化设计。仿真结果表明了该方法的有效性和实用性。

This paper presents a new approach to the optimization of digital filter design by using the MultiCriterion Satisfactory Optimization (MCSO) method and also introduces the computing model and algorithm for this optimization method. We define a satisfactory rate function to evaluate the performance of the digital filter in a pragmatic way. The application of the multicriterion satisfactory optimization for the design of fransition band of the finite impulse response (FIR) digital filter will demonstrate the utility and efficiency of this method.
