摘要

提出并分析了一种用于室内衰落多径信道的集中式话音/数据综合无线网络。它可以作为一个独立的系统或作为蜂窝网络中的一个单元运行。通过可移动边界帧轮询协议集成上行链路中的语音和数据分组，以优化给定数量的语音终端的数据流量吞吐量。下行链路是一个简单的时分复用(TDM)系统。在衰落多径室内信道中，系统在两种传输速率之间动态切换，并采用多天线实现最大吞吐量。采用三种不同的技术，分析了系统的吞吐量和延迟特性。给出了一个简单的公式，给出了语音用户数、小于10ms延迟的数据流量和系统平均传输速率之间的近似关系。结果与蒙特卡罗计算机模拟结果进行了比较

An integrated voice/data system for mobile indoor radio networks using multiple transmission rate

A centralized, integrated voice/data radio network for indoor fading multipath radio channels is proposed and analyzed. It can operate as a stand-alone system or as a cell in a cellular network. The packets of voice and data in the uplink are integrated through a movable-boundary framed-polling protocol to optimize the throughput of the data traffic for a given number of voice terminals. The down link is a simple TDM (time division multiplexing) system. The system dynamically switches between two transmission rates and uses multiple antennas to maximize the throughput in the fading multipath indoor channel. Using three different techniques, the throughput and delay characteristic of the system are analyzed. A simple equation is given to provide an approximate relation between the number of voice users, the data traffic with less than 10-ms delay, and the average transmission rate of the system. The results are compared with those of Monte Carlo computer simulations.<>
