摘要

本文揭示了OFDMA系统的基本工作原理。同时，还揭示了该系统的主要特点是多用户访问。本文将OFDMA与CDMA、OFDM等其他系统进行了比较，说明了OFDMA在连接和数据传输方面的优越性。此外，我们还将修改上行或下行连接的类型。例如，对比OFDMA系统的运行模型，分析了一种基本模型。最后，介绍了正交频分多址的工作原理、优点、应用和类型。

Advanced metering infrastructure. State-of-art LTE based on OFDMA

This paper discloses the basic operation of OFDMA system. Also, it discloses the main features of which is a multi-user access. OFDMA has been compared to other systems, such as CDMA or OFDM system, and this article shows the superiority of OFDMA in connection and in data transmission. In addition, we will also revise up or down connections' types. For instance, a type of basic model is analyzed comparing to the operating model of OFDMA system. Finally, this paper discloses the operation, advantages, applications and types of pair connection regarding to Orthogonal Frequency Division Multiple Access.
