一种基于槽分的无线多媒体网CDMA调度算法

Slot-based CDMA Scheduling Algorithm for Wireless Multimedia Network

在未来的无线多媒体网络中，将有各种不同的通信类交织在一起，它们各自有最大容错位出错率（BER）．针对此问题，给出了一种适于无线多媒体网络的基于槽分的CDMA调度算法．由于无线通信系统中可获得的带宽是最宝贵的资源，算法的主要目标是使网络流量最大并使分组（pscket）损失最小，并通过对BER、优先级等参数的优化实现了算法的目标．调度实例证明，算法具有使负载平衡的特性．

In future wireless multimedia network, there will be a mixture of different traffic classes which have their own maximum tolerable bit error rate(BER)requirements. In this paper, a slot-based CDMA scheduling algorithm is designed for wireless multimedia network. Considering that the available bandwidth maybe the most precious resource in a wireless communication system,the main objects of our scheduler are to maximize the throughput and to minimize the packet losses.
