Abstract

An effective design of successive joint blind multi-target (MT) adaptive antenna array (AAA) and interference cancellation is presented for multi-user detection of DS-CDMA. The MT-AAA employs the adaptive block size least square-constant modulus algorithm (LS-CMA) with pre-despreading at each antenna element combined with a simple weight adaptive canceller. The combined process is repeated successively for the detection of all users without any knowledge of the channel or training sequences. It is shown to utilise the advantages of both techniques and provides improved performance in fading channel for the near-far problem, in-beam interference, and a high number of users.
