【摘要】 支持向量机作为非线性多用户检测器,可以利用较少的训练数据,检测经过瑞利(Rayleigh)衰落的同步CDMA通信系统信号.计算机仿真结果表明,在多普勒频移不同的瑞利衰落信道下,这种多用户检测算法误码率性能优于线性最小均方误差(MMSE)算法.更多还原

【Abstract】 SVM is proposed as a nonlinear multiuser detector (MUD) from a relatively small training data block to detect synchronous CDMA signals in multipath Rayleigh fading channel. Computer simulation is used to study this SVM MUD, and the results show that its performance is superior to linear MMSE MUD.更多还原
