毫米波室内传播的场强测量

Field strength measurements on millimeter wave indoor propagation

介绍了毫米波室内传播的场强测量。通过对测量的数据进行处理，可得无论使用全向天线还是定向天线作为接收天线，路径损耗指数都约等于２。慢衰落的累积概率分布符合对数正态（Ｌｏｇ－ｎｏｒｍａｌ）分布。快衰落的累积概率分布在没有直达波（ＮＬＯＳ）的情况下符合瑞利（Ｒａｙｌｅｉｇｈ）分布，而在有直达波（ＬＯＳ）的情况下，如果使用全向天线则趋向瑞利分布，使用定向天线则符合莱斯（Ｒｉｃｅ）分布。

In this paper, the experimental study on millimeter wave(Ka Band)indoor propagation is presented.Based on the measured field strength, it is found that the path loss exponent is approximately of 2, regardless of what kinds of antenna are used.The cumulative distribution of slow fading agrees to the log normal distribution,while that of fast fading agrees to the Rayleigh distribution in NLOS case or the Rice distribution in LOS case.
