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。
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3GPPWCDMA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。
A simulation framework for VoIP speech quality in wideband mobile communication systems was intended to outline, which is composed of wireless link simulation, system performance simulation and speech quality simulation. 提出了宽带移动通信系统中的IP电话语音质量的仿真方法。整个仿真平台由无线链路仿真、系统级性能仿真和VoIP语音质量仿真三部分组成。
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。
