摘　　要：随着物联网技术以及无线传感网的快速发展,远程医疗(Telemedicine)系统在国内外获得了广泛的研究和应用。Telemedicine会诊旨在患者和医院之间建立起全新的联系,由于信息是在无线系统中进行传输的,从而存在码间干扰。为了提高通信质量,文中着眼于Telemedicine物理层的技术研究,概括介绍了一种基于RLS的分布式盲均衡算法,并在此基础上基于提高算法运行速度,提出了一种新的自适应算法,旨在不失其性能指标的前提下,使其运算复杂度大大降低,有效地克服了传统自适应算法的收敛速度慢的缺点。With the rapid development of the Intemet of Things technology and wireless sensor networks, Telemedicine system has a wide range of research and application all over the world. Telemedicine consultation between patients and hospital aims to establish new links in place. Since the information is transmitted in a wireless system,so them exist inter-symbol interference. To improve the communication quality,looking at the technical study of the Telemedicine physical layer, provide an overview of a distributed blind equalization algorithm which based on RLS, and also propose a new adaptive algorithm without losing its performance under the premise to reduce its run-time. As a result, the operation complexity is greatly reduced, and effectively overcome the convergence speed of the shortcomings
