摘要

针对功率控制

提出一种利用模糊规则的自适应LMS信道估计算法

通过将信道增益大小和前后变化值的大小划分为若干模糊集

建立将自适应算法和经验值相结合的自适应滤波器

使算法具有对低轨信道时变特性一定的适应性。仿真结果表明了算法的有效性。

Abstract

A novel adaptive LMS filter algorithm based on fuzzy rules was proposed.Through building many fuzzy sets over the space of channel gained value and the increment value of channel gain

in addition to the setting of fuzzy rules

an adaptive algorithm incorporated with human experience was set up

which was adaptive to the time

aring character-istics of LEO satellite channel.The results of the simulation validate the algorithm.
