| 摘 要： | 提出了一种自适应信道均衡的方法,它利用粒子群优化算法对均衡器系数进行自适应调整.由于粒子群优化算法具有实现简单、性能函数的单调性强、搜寻全局最优解的能力强等优点,将其用于自适应信道均衡将会改善传统均衡器均衡效果不理想的问题.仿真结果表明,该方法实用有效,在信道失真较大和最优解搜索精度方面表现出了优越性.

| Abstract: | This paper presents a new method for adaptive equalization, using particle swarm optimization algorithm to adjust the coefficients of the equalizer, Due to its simple realization, good performance function monotonicity and powerful global search, PSO can improve the adaptive equalizer greatly. The experimental results proves its availability and its great advantages when much deeper distortion occurs. |
