摘要

在两种室内场景下，评估了使用60 GHz频段的移动/无线宽带数字无线电系统在不同天线配置下的传输性能。结果表明，对于相同的均衡努力，最大可实现载波比特率(CBR)强烈依赖于天线配置。在移动终端(MT)和基站收发器(BST)上使用双锥喇叭天线，中型房间的CBR可达40- 50mbit /s，大型房间的CBR可达20mbit /s，而在房间的两个较窄的侧壁上使用两个喇叭天线时，CBR可达100mbit /s。此外，提出了一种基于信道时间色散估计最大CBR的简单方法。给出并讨论了沿房间的几种MT位置的仿真结果。

Transmission capacity of a broadband wireless radio link

The transmission performance of a mobile/wireless broadband digital radio system, using the 60 GHz band, is evaluated for different antenna configurations in two indoor scenarios. It is shown that for the same equalization effort the maximum achievable carrier bit rate (CBR) strongly depends on the antenna configuration. A CBR of 40-50 Mbit/s in a medium size room and 20 Mbit/s in a large room using biconic horn antennas at the mobile terminal (MT) and at the base station transceiver (BST) is achievable, while this limit increases up to 100 Mbit/s when using two horn antennas located in the two narrower lateral walls of the room. Moreover, a simple method to estimate the maximum CBR based on the channel time dispersion is presented. Simulation results for several MT positions along the rooms are presented and discussed.
