宽带移动通信系统基于正交频分复用（OFDM）传输技术，原因如下：(1)。本文的目标是设计灵活的数据链路控制（DLC）协议，该协议将时变无线电信道（由信道传递函数描述）的信息与来自不同应用程序的恒定和可变数据速率的传入数据流结合起来。其目标是在优先级和吞吐量方面全面满足所有无线终端的服务质量（QoS）要求，并提高系统的平均吞吐量。
Wide-band mobile communication sys- tems are based on the Orthogonal Frequency Division Multiplexing (OFDM) transmission technique for several reasons (1). The objective of this paper is the design of flexible Data Link Control (DLC) protocols, which combine the information of the time variant radio chan- nel (described by the channel transfer function) and the incoming data streams from different applications with both, constant and variable data rates. The goal is to ful- fil the quality of service (QoS) requirements in terms of priority and throughput for all wireless terminals and to improve the average system throughput.
