The data transmission performance of Bluetooth is analyzed, including the Packet Error Rate(PER) ( PER ) and throughput of ACL data packet under the inter-piconet interference. 文中分析了蓝牙设备在微微网干扰下的数据传输情况,具体分析了ACL数据分组在微微网同频干扰下的丢包率及吞吐量。
The link layer packet error rate and transmission delay are derived to evaluate this scheme. 推导了采用该方案时无线链路的误包率和包的传输时延的表达式。
Existing network management system can access each activities interface of network device performance data, including : data receiving and sending traffic, bandwidth utilization, packet loss rate, packet error rate. 现有的网络管理系统能够获取网络中每个设备的各活动接口上的性能数据,包括:数据接收和发送流量、带宽利用率、丢包率、误包率等。
Network coding technology can effectively improve the system throughput, but it also can increase the packet error rate to some extent. 网络编码能有效提高系统吞吐率,但在一定程度上会增加误包率。
To achieve same target encoder packet error rate under different fast fading channel conditions, fixed channel quality to data rate mapping pattern would not work well in time division multiplexed wireless packet data transmission. 为在不同快衰条件下获得相同的编码器分组目标差错率,固定的信道质量与数据速率之间映射方式将不能在时分的无线数据传输中很好地工作。
