Support Vector Machine Multiuser Detector for TD-SCDMA Communication System in Multipath Channels

摘要

TD-SCDMA, a part of the third generation mobile communication standards IMT2000 and UMTS is described. A nonlinear multiuser detector based on Support Vector Machine (SVM) is presented and the performance is compared with traditional linear detector. The presented detector can approach optimum multiuser detector than the other linear detectors by using the Midamble of TD-SCDMA. The results of simulation show the feasibility and validity of this detector in multipath channel.
