正交频分复用（OFDM）系统是一种多载波系统，其利用并行处理技术允许在许多的同时传输数据的密切隔开，正交子载波。快速傅立叶逆变换（IFFT）和快速傅立叶变换（FFT）在传统的OFDM系统被用于复用信号一起和解码信号在分别的接收机。本文研究的性能离散傅立叶变换正交基频分复用（DFT-OFDM）。

无线应用协议（Wireless Application Protocol，WA P）是WA P论坛经过不断努力得到的成 果，它提供了一个业界技术规范，以便开发出适用于各种无线通信网络的应用和业务。WA P 论坛的工作范围就是为各种业务和应用制定一系列的技术规范。无线市场正在快速增长，新 的用户不断增多，新的业务不断涌现。为了使运营商和生产者能够从容面对先进业务、多种 类业务和快速、灵活的业务生成等诸多的挑战， WA P规定了一系列传输层、会话层和应用层 协议。-Wireless Application Protocol (Wireless Application Protocol. WA P) P Forum WA is a result of efforts the results, it provides an industry technical standards, developed to apply to all kinds of wireless communication networks and business applications. WA P scope of the work of the Forum is for various business applications and formulated a series of technical standards. Wireless market is growing rapidly, new users are increasing and new business continued to emerge. To enable operators and producers to calmly face the advanced business, and more types of business fast, flexible service creation and many other challenges, WA P provides a series of transport layer, session layer and application layer protocol.
