摘要

我们研究并比较了TDMA、CDMA和ALOHA以及混合TDMA/CDMA、ALOHA/CDMA和ALOHA/TDMA作为蜂窝交互式电视架构中返回信道MAC协议的可能候选方案。根据用户数量和所涉及的流量速率，对上述MAC方法之间的访问特性进行了比较分析。所研究的多路访问技术的性质，特别是混合访问技术，不允许进行客观的性能比较，而是进行简单和近似的比较。对每种方法的优缺点进行了回顾，并为最可行的解决方案提供了实施指南。

Evaluation of multiple access methods for the MAC protocol of the return channel in a cellular interactive TV architecture

We study and compare TDMA, CDMA and ALOHA as well as hybrid TDMA/CDMA, ALOHA/CDMA and ALOHA/TDMA as possible candidates for the MAC protocol of the return channel in a cellular interactive TV architecture. A comparative analysis of the access characteristics between the previously mentioned MAC methods is provided on the basis of the number of users and the traffic rate involved. The nature of the multiple access techniques examined, especially for the hybrid ones, does not allow for making objective performance comparisons but rather simple and approximate ones. The advantages and disadvantages of each method are reviewed and implementation guidelines are provided for the most feasible solutions.
