Contour-Based V2V Channel Cluster Identification Algorithm

In this paper, a Contour-based Cluster Identification (CCI) algorithm is proposed to identify the clusters in Concatenated Power Delay Profiles (CPDPs). To predict the characteristics of clusters, we introduce four methods to the three-fold CCI algorithm. Our new methods increase identification accuracy with greatly decreased computational complexity from 2-D to 1-D Hough-transform searching. The accuracy of prediction methods and the efficiency of the CCI algorithm are both confirmed by simulation results.
