摘要

基于26 GHz室内通信测量数据对人体阻挡衰减特性进行了研究。在Vogler多重刃形绕射场强计算的基础上，提出了包含二射线和四射线的多个人体阻挡绕射模型。结果表明，四射线人体阻挡衰减模型与实验数据非常吻合，信道测量带宽为1 GHz时的人体绕射衰减略大于带宽为500 MHz时的衰减。在人体沿发端(TX)和收端(RX)连线平移过程中，人体位于连线中间位置时衰减最小，人体离RX端最近时衰减最大。在多人体穿过视距线阻挡测量中，人体横向穿过视距线(人脸正面面向RX喇叭口)比人体侧向(人脸侧面面向RX喇叭口)穿过视距线时衰减大。此外，人体阻挡数目越多，衰减越大，人体阻挡数目每增加1人，阻挡衰减增加5～8 dB。本文结果为分析26 GHz人体衰减特性和该频段毫米波无线通信系统设计提供有用信息。

Abstract

Based on 26 GHz indoor channel measurements

the blockage attenuation of human bodies was investigated. 2-ray and 4-ray human blockage models were proposed by calculation of the Vogler's multiple knife-edge diffraction field. Results show that 4-ray model fits quite well with measurement data. Human block attenuations are slightly bigger with 1 GHz than with 500 MHz bandwidth. In the blockage measurement of one person moving along the connec-tion line between the transmitter (TX) and receiver (RX)

the smallest attenuation is found when the person is located at the middle of the connection line

and the biggest attenuation is observed when the person is nearest from the RX position. In the blockage measurements by multiple human bodies

the attenuation is bigger in the cases which the persons cross the TX-RX connection line with their front faces directed to the horn aperture at the RX than the cases with their lat-eral faces directed to the RX horn aperture. The blockage attenuation is larger with the increase of person numbers

about 5～8 dB more attenuation per person. The results can be used for design of mm-wave 26 GHz indoor communi-cations systems.
