摘要 针对单信道不能解决并发传输的问题,在超宽带系统的接入控制中采用多信道方式,根据信道最大利用率的原则决定哪些分组可先传送.对原有的接入控制设计进行了适用于超宽系统特点的改进,通过退避一段随机时间再来监听信道.在半双工方式下采用单收发器方式进行系统设计,每个节点依据服务质量需求选择确定的分组,分组信息广播到所有节点,所有信息在信号产生阶段收集以减小系统额外开销.仿真结果表明,改进的设计在业务量高时传输性能更好. Multi-channels were used in the connection admission control of UWB（ultra wideband） systems to transmit data concurrently in order to solve the problem of single channel. The packets with the most channel efficiency were transmitted. A new admission control design adaptive for UWB systems was developed, and back off time was randomly used to sense the channel. We investigated and simulated the complete system design considering the system with single transceiver and in a half du plexing mode, each node selects predetermined number of packets from each traffic flow according to the quality of service requirements, packet information is broadcast to all nodes. All required information is collected in the signaling process to reduce the overhead of the systems. Simulation results indicate that the improved design have better performance when the channel load is heavier.
