摘要
首先推导了基于可变扩频增益 CDMA系统的多级业务的接纳准则 ,其次 ,详细研究了视频业务和语音业务的接入问题。通过理论分析和实验仿真得出了一些对无线多媒体业务接入控制的设计具有一定借鉴意义的结论。
An admission criterion for multiclass services access is deduced based on variable spreading gain CDMA(VSG CDMA) systems. The access problem of voice services is discussed in detail. By theoretical analysis and simulation, some conclusions are obtained which are significant and valuable for the design of access control of wireless multimedia communication systems.
