متن کاملA new MUD algorithm for smart antenna
We propose a new adaptive beamforming technology for multi-user detection applications. The algorithm requires no reference signal. It consists of two stage processes. The function of the 8rst stage is to scan initial incident directions of users. At the second stage, adaptive beamforming algorithms, for each detected user at the 8rst stage, are applied to 8nd the exact users’ signals. Computer...
