Demonstrating Advantages of Smart Antennas in Indoor Wireless Communications Systems

室内无线通信系统的性能受到多径信号传播的不利影响。当接收信号降至某一电平以下时，通常的做法是接收站请求发射设备增加其输出功率。这一行动的不利影响是降低了便携式收发机的电池寿命，向用户辐射更多的功率并增加干扰。本项目的目的是演示一种保持高质量通信链路的替代方法。该方法使用智能天线系统来缓解多径和干扰的不利影响。

The performance of indoor wireless communications systems is adversely affected by multi-path signal propagation. When the received signal drops below a certain level, the usual practice is that the receiving station requests the transmitting device to increase its output power. An adverse effect of this action is a reduced life of battery of a portable transceiver, more power being radiating towards users and an increase of interference. The aim of this project is to demonstrate an alternative method of maintaining good quality communication link. The proposed method employs a smart antenna system to mitigate adverse effects of multi-path and interference.
