| Abstract: | This paper changes the problem of blind multiuser detection of the communication system of CDMA to a quadratic programming problem with some constraints, and gives a new method of blind adaptive multiuser detection for CDMA by solving the quadratic programming problem using the e-approximation algorithms. The simulation results show that the proposed method not only possesses stronger capability of suppressing interference, but also converges very quickly which implies that it is especially suitable for time varying channels. |
