1.前言近年来,由于在办公大楼、会议中心、医院、工厂和公寓内频繁使用室内数据和话音的通信,使室内无线电波传播成为一个研究热门。已开展过功率损耗、RMS 延迟扩展的统计和极化分集方面的研究来试图模拟室内无线电信道,但尚未深入地研究过发射机和接收机之间人员来往所引起的室内无线电传播特性的时变效应。
1. Introduction In recent years, due to the frequent use of indoor data and voice communications in office buildings, convention centers, hospitals, factories and apartments, the spread of indoor radio waves has become a research hotspot. Studies of power loss, RMS delay spread statistics, and polarization diversity have been attempted to simulate indoor radio channels, but time-varying indoor radio propagation characteristics due to human-to-human transmissions between transmitters and receivers have not been studied in depth effect.
