一种适用于无线ATM通信的差错控制方案

An Error Control Scheme for Wireless ATM Communications

  • 摘要: 研究了无线ATM通信的差错控制方案,提出了应根据多媒体业务类型、速率等参数,以及移动环境等,自适应地选择合适的差错控制技术和参数的思想。文中提出的差错控制方案主要包括FEC (可变深度的交织、卷织码、BCH码)和限时/非限时SARQ等技术,计算机仿真结果表明了所提方案的有效性。

     

    Abstract: This paper introduces an error control scheme for wireless ATM communications.In our scheme,the network can adjust the error control parameters according to multimedia traffic types,source bit rate and wireless mobile enviornment.The proposed error control scheme primly consists of FEC and SARQ.Simulation results indicate that the scheme can meet the multimedia QoS requirement well in wireless ATM communications.
