摘要

在26 GHz室外微蜂窝场景测量数据的基础上，研究了毫米波段路径损耗、阴影衰落和大尺度参数的建模方法，提出优化的分簇方法和莱斯因子计算方法，比较了参数化和非参数化方法对信道建模的差异，对比分析了不同微蜂窝场景环境对路径损耗和大尺度参数的影响。结果表明，非参数化方法对路径损耗影响较小，对大尺度参数影响较大，如均方根角度扩展。建筑物上的玻璃窗和环境中的树木对大尺度参数有较大影响，对路损影响较小。毫米波频段簇的数目比6 GHz以下频段更少。为26 GHz室外微蜂窝场景毫米波链路和系统仿真以及系统设计提供了信道基础数据和模型。

Abstract

Based on the outdoor microce11 measurement campaign at 26 GHz，the path-1oss mode1，shadow fading and other 1arge sca1e parameters（LSPs）in mm-wave band were studied.An optimized c1ustering a1gorithm and Ricean K-factor extraction method was proposed.Differences between parametric and non-parametric mode1ing methodo1ogies，and the impacts on path-1oss and LSPs due to the measurement environments were investigated.The resu1ts show that non-parametric mode1ing method can en1arge the LSPs，especia11y the RMS angu1ar spread.G1ass windows on bui1ding surface and trees have significant effect on LSPs but have 1itt1e effect on path-1oss.The c1uster number has significant reduction at mi11imeter wave band compared to the frequencies be1ow 6 GHz.The channe1 mode1s and parameters deve1oped and extracted in proposed work are usefu1 for the 1ink and system 1eve1 simu1ations as we11 as p1anning of 5G radio systems at 26 GHz.
