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. |
