基于循环神经网络的宽带CDMA系统的功率控制

W-CDMA Systems Power Control Based on Circular Neural Networks

在CDMA系统中,远近效应是一个重要的技术难题,克服该难题的有效措施是系统进行功率控制。该文根据Hopfield循环神经网络的思想,把功控问题转化为离散的Hopfield神经网络,由此给出了一种新的功率控制算法,它能控制移动用户发射功率的平衡,且有较强的Robustness性质,易于工程实现。

This paper transfer the uplink power control problem of W-CDMA mobile stations to a discrete circular Hopfield neural network, and presents a new power control algorithm implementation on the uplink. It can control the power to balance, effectively diminish the near-far effect. The simulation of the algorithm on CDMA uplink shows that it has good robustness and is easy to be implemented.
