A Multiuser Detection Using Adaptive Eigenvalue Decomposition Based on First order Perturbations

XUE Qiang,DU Zhi min,WU Wei ling (Beijing University of Posts & Telecommunications,PO.Box 181,Beijing 100876,China)  
In this paper,we proposed a new blind adaptive approach used in multipath channel.This approach performs an eigendecomposition of autocorrelation matrix,and uses Least Mean Square to estimate channel adaptively.Experiments and simulations show that the approach converges faster and has a better performance,so it is a better blind adaptive multiuser detection.
