码分多址(CDMA)和时分多址(TDMA)的大论战有力地推动了第二代和第三代数字移动通信系统空中接口的讨论.本文提出了一条合理比较这两种多址方式的原则.全文并未涉及技术细节以及实施方面的情况,而是讨论了一些许多运营公司都感兴趣的问题,如抗干扰能力,信道中最大的可靠信息速率,信道耐损性及对无线链路控制的影响等.深入的分析表明,无论是CDMA还是TDMA都不是完美的,只能说两种方式各有利弊.
The debate between Code Division Multiple Access (CDMA) and Time Division Multiple Access (TDMA) strongly promoted the discussion of the air interface of the second generation and third generation digital mobile communication systems.This paper presents a reasonable comparison of these two multiple access methods Rather than dealing with technical details and implementation aspects, the paper discusses some of the issues that many operating companies are interested in, such as anti-jamming capability, maximum reliable information rate in channels, channel resistance, The impact of control, etc. In-depth analysis shows that neither CDMA nor TDMA is perfect, and it can only be said that there are advantages and disadvantages in both approaches.
