摘　　要：根据ATM无线链路组网需求,提出了适合无线链路反向复用的编码及动态容量调整技术。该技术适用于利用微波、散射和卫星等传输手段进行ATM/MPLS无线机动组网,编码纠错门限为2×10-3,当通信节点无线传输距离增大或信道传输质量变恶劣时,通过动态容量调整技术自动降低信号速率以提高业务传输质量,该项技术特别适合新一代宽带网络。According to the latest inverse multiplex of ATM and codec technologies, a new IMA control and transport method has been developed, which can overcome signal fading of the wireless link such as scatter, satellite and microwave channel, and then adaptively adjusts the link capacity, as well RS codec is applied which can works very well unless channel error bit rate is more than 2 x 10-3. Due to large distance or signal fading between nodes, the quality of services can be improved greatly by automatically adjusting the link capacity and error control. This technology can be widely used in wireless connected ATM/MPLS broadband network.
