摘要

本文介绍了蜂窝SDMA/TDMA系统在可变比特率业务下的性能。我们采用时隙分配算法，既考虑新用户的信号质量，又考虑活跃用户的信号质量，为新用户分配时隙。为了支持不同的多媒体业务，可以根据业务质量要求自适应选择调制方案。在蜂窝环境下，对不同业务的阻塞概率、强制终止概率和平均延迟进行了评估。

Performance evaluation of cellular SDMA/TDMA systems with variable bit rate multimedia traffic

This paper presents the performance of cellular SDMA/TDMA systems with variable bit rate traffic. We employ a time slot assignment algorithm, which assigns a time slot to a new user considering not only the signal quality of the new user, but also that of active users. To support different multimedia services, a modulation scheme is adaptively selected according to the QoS (quality of service) requirement. Blocking probability, forced termination probability, and average delay of different services are evaluated in a cellular environment.
