Multiuser detection is the key technology to suppress the multiple access interference in spread spectrum system.This paper introduces the principle of subspace-based blind multiuser detection.The algorithm gets the signal sunspace by the space decomposition,and then the decorrelation multiuser detection is given by the eigenvectors and the eigenvectors of the signal subspace,and analyzes the performance of this method.Through numerical simulation,it can be proved that subspace-based blind multiuser detection performs well in respect of efficiency and near-far resistance.We can conclude that subspace based blind implementing is a promising multiuser detection method.
