A Fuzzy Clustering Algorithm Based on Multipath Component Traiectory for Millimeter Wave Radio Channels
文献摘要：
Time-varying channel modeling plays an important role for many applications in time-variant scenarios,while most clustering algorithms focus on static channels and cannot accurately model the chan-nel time-evolution properties.In this paper,a fuzzy clustering algorithm based on multipath component(MPC)trajectory is proposed.Firstly,both the dis-tance and velocity similarities of the MPCs in differ-ent snapshots are taken into account to track the MPC trajectory,in which the fuzzy scheme and a kernel function are used to calculate the distance and velocity similarities,respectively.Secondly,a fuzzy MPC tra-jectory clustering algorithm is proposed to cluster the MPCs in multiple snapshots.The MPCs in a snapshot are clustered according to the membership,which is defined as the probability that a MPC belongs to dif-ferent clusters.Finally,time-varying channels at 28 GHz are simulated to validate the performance of our proposed algorithm.The results show that our pro-posed algorithm is able to accurately identify the clus-ters in time-varying channels compared with the exist-ing clustering algorithms.
