In modern warfare a great deal of information needs to be transmitted among different platforms which raises a requirement for wideband data link .

现代战争中大量信息在不同平台间传送，需要开发 宽带数据 链。

In contrast to ATM network transmission link which is characterized by wideband low bit error rate and high transmission bite rate wireless link technologies can provide limited bandwidth unreliable transmission channel with high bit error rate .

ATM传输和交换以 宽带、低误码率和高传输速率的传输介质为前提，可以提供多媒体服务和广泛的信息 接入。而无线 信道的传输特点是带宽受限、信道传输质量差和传输误码率高。

Wideband network systems protocol stack includes physical layer data link layer network layer and application layer . The data link layer mainly completes multiple access priority queues data segmentation and reassembly reliable transmission and other functions .

宽带网络系统协议栈分为物理层、数据 链路层、网络层以及应用层，数据链路层主要完成多址接入、优先级队列、数据分段及重组、可靠传输等功能。

A combined power control and data rate adjustment scheme with Minimum Mean Square Error ( MMSE ) receiver for the 3GPP Wideband Code Division Multiple Access ( WCDMA ) reverse link is proposed .

该文针对3GPP WCDMA系统的反向 链路，提出了一种基于MMSE接收机的功率和数据速率相结合的控制算法。
