It assumes that the quality of communication link is high, and link error rate is very low, only can congestions or a large delay cause packet loss. 它假设通信链路都是高质量的,链路错误率极低,只有拥塞或大延时才能导致包的丢失。
The simulation results show that the proposed algorithm can increase throughput and decrease the cost of cache, especially, the network throughput enhances 2.3 times and the cost of cache reduces by 60 % compared with Snoop when the link error rate is high. 仿真结果显示,采用所提算法可以提高网络吞吐量,降低缓存用量,特别是当无线链路误码率较高时,其网络吞吐量比Snoop算法可提高2.3倍,而缓存用量只有Snoop算法的40%。
Multiple Input Multiple Output ( MIMO ) wireless technology can effectively improve system capacity and reliability. By taking the advantages of spatial multiplexing and spatial diversity, MIMO technique could increase the data transfer rate, while decreasing wireless link error rate. 多输入多输出(MIMO)技术能够有效提高无线系统的容量和可靠性,通过空间复用,增大数据传输速率,通过分集减小无线链路误码率。
The random jitter of the beam will impact the normal communications due to the narrow laser beamwidth. It increases link error rate and affects the quality of communication link. 由于信号光束较窄,光束的瞄准误差会增加链路的误码率,影响了链路的通信质量。
Firstly, the Casablanca discriminator is adopted in receiver to classify wireless losses from congestion losses to solve the problem of high link error rate. 首先,针对卫星网络高误码率的特点,在接收端采用了Casablanca分类器区分链路丢包和拥塞丢包。
