This paper presents the particle swarm optimization-based design of a wideband comb compensator with a sinewave magnitude response. First, the magnitude response of the compensator is presented as a sum of two sinewave functions, where the amplitudes of sinusoidal functions are the design parameters. Next, a particle swarm optimization is applied to find the design parameters which result in a minimum of the absolute value of passband deviation of the compensated comb, for a given set of comb parameters. The resulted comb compensator has two multipliers and six adders. Next, the design parameters are expressed as a sum of powers of two, in order to get a multiplierless design. In order to demonstrate the advantages of the proposed designs, both multiplier, and multiplierless designs, are compared with the state-of-the-art.

本文提出了一种基于粒子群优化的具有正弦波幅值响应的宽带梳状补偿器设计。首先，将补偿器的幅度响应表示为两个正弦波函数之和，其中正弦函数的幅度是设计参数。接下来，对于给定的一组梳形参数，应用粒子群优化算法找到设计参数，这些参数可使补偿梳形的通带偏差绝对值最小。所得的梳状补偿器具有两个乘法器和六个加法器。接下来，将设计参数表示为2的乘方之和，以得到无倍数设计。为了证明所提出设计的优点，将乘法器和无乘法器设计都与最新技术进行了比较。
