| Abstract: | The Matlab-based simulation platform are set up to realize fingerprint data collection,database creation,matching positioning and so on.Comparison tests are also made among the nearest neighbor algorithm,K nearest neighbor algorithm,and weighted K nearest neighbor algorithm to analyze their positioning effects in GSM-R networks.Through revising GSM-R network parameters,the size of fingerprint,and so on factors,the positioning performance of each algorithm are compared. |
