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

Additional Information: The paper describes an effective design combining blind adaptive antenna array and interference cancellation to increase the capacity and performance of CDMA-based mobile communication systems. The joint algorithm achieved the advantages of both techniques and implemented without the need for any channel knowledge or training sequences. Competitive field required rapid publication in this leading journal with high impact factor.The work presented here and recent advances within the group are providing for more future collaborations with industry and academia.
