摘要
设计一种改进的数字自动增益控制系统。基于自动增益控制环路和负反馈原理,采用指数的泰勒级数展开式直接对指数进行近似运算,在硬件中将除法运算简化为逻辑右移。仿真结果表明,该设计方法收敛速度快、硬件结构简单且资源消耗低。
An improved digital automatic gain control system is designed. Approximate algorithm of the index can be reached by the stage expansion which is based on the index of Taylor series. In the hardware, the straight-forward shift right logical can achieve the division operation. Simulation results show that the improved method has efficient convergence, simple structure, and low resource consumption.
