【Abstract】 Support vector machine(SVM) is proposed as a nonlinear multi-user detector(MUD) from a relatively small training data block to detect CDMA signals.Because of the steady capability,it is used in MUD,then it is improved in the complexity and rate of operation.The major characteristics and applications of SVM to multi-user detection is analyzed,and several improved SVM detections are generally introduced.更多还原
