摘要 该文在语音与数据混合的CDMA无线网络中提出了一种新的煤质访问控制(MAC)协议MSADQ(Minislot Signaling Access based on Double Queue)。该协议基于分布队列及冲突解决算法,通过对PN码字的有序管理,从而大大减少随机竞争的冲突,降低多址接入干扰,节省PN码码资源。提出了码字分配算法和队列管理算法,对语音和数据业务进行QoS保证。对协议的性能进行了仿真,并与其他两种预约协议进行了比较,结果表明,MSADQ/CDMA协议使用较少的PN码字却仍然有很好的性能。
Abstract：In this paper, a new packet medium access control protocol, namely, Minislot Sig-naling Access based on Distributed Queues protocol is proposed in voice and data integration CDMA network (MSADQ/CDMA). Through proper manage of the PN codes, the number of random competition collisions reduces greatly, the Multiple Access Interference (MAI) de-creases, and the code resources are saved. Computer simulations are carried out in voice and data integration networks, and comparisons with other two reservation protocols are devel-oped, which show that MSADQ/CDMA protocol occupies less PN codes, but still has very good performance.
