摘要

本文将以码合并形式的自适应分组解码应用于某无线多业务CDMA环境。语音和分组交换数据都被考虑在内。数据业务采用开槽aloha类型的码分随机访问协议。在信道和调制方面，中上衰落发生在BPSK或DBPSK调制的数据上。在多对一链路即无线环境中的反向链路上，采用了一种基于D和R/sub 0/参数的分析易于处理的简单模型。对数据终端的队列延迟和信道延迟进行了分析。实践证明，该系统具有很高的灵活性，可以适应不同业务需求的不同业务

Adaptive packet decoding in a wireless multiservice CDMA environment

In this paper, adaptive packet decoding in the form of code combining is applied in a certain wireless multiservice CDMA environment. Both voice and packet switched data are considered. The data services employ a slotted ALOHA-type of code division random access protocol. Concerning the channel and modulation, Nakagami fading takes place on BPSK, or on DBPSK modulated data. An analytically tractable and simple model based on the D and R/sub 0/ parameters is employed on the many to one link i.e. the reverse link in a wireless environment. Both queueing delay and channel delay analysis on data terminals are presented. It is shown that this system offers a high flexibility in accommodating multiple services with different traffic requirements.<>
