26 GHz室内簇的时变特性及建模研究
Characteristics and models for indoor time-varying clusters at 26 GHz
摘要
Abstract
In this paper, the characteristics and models for indoor time-varying clusters at 26 GHz are studied based on large scale single input multiple output(SIMO) measurements.The algorithm for finding clusters in METIS (Mobile and Wireless Communications Enablers for the Twenty-twenty Information Society) project was improved.In order to remove the effect of the rays in a cluster and the noise, the envelope for a power-delay-profile(PDP) is calculated before counting number of clusters, which is good to get a more reasonable result.Based on the measurement, the variation of number of clusters with time is modeled as a normal distribution with the mean and variance to follow a quadratic function with respect to the time intervals.关键词
