固定比特速率 meaning in English

cbr

One suits for non real time traffic and the other for real time traffic . in this paper , we focus on m - lwdf which is an interesting algorithm for providing streaming services on hsdpa because it includes in the priority computation not only the instantaneous channel quality experienced by the user , but also the packet queuing delay
其次,按照支持实时和非实时业务来分类讨论无线分组调度算法,确定支持实时业务的m - lwdf算法为本文重点研究对象,分析了在固定比特速率情况下m - lwdf算法的性能,并对其作了修正。
Simulation results show that : i ) the m - lwdf algorithm is a viable solution for scheduling streaming flows in hsdpa ; ii ) this algorithm is unfair because it provides a better qos to users under favourable propagation conditions ; and iii ) a maximum node b queuing of 2 ~ 3 seconds represents a good compromise between cell throughput and delay jitter introduced in the node b for streanming
仿真结果表明, m - lwdf算法适合于hsdpa中流用户的调度服务,但它是一种不公平的算法,总是选择为信道条件好的用户提供更好的qos 。当应用于固定比特速率流业务时,对m - lwdf算法作了一些修改,使得修正后的算法在用户公平性上有了改进,但是不可避免地引起了系统吞吐量的下降。
