Abstract :
In this paper, we propose two adaptive antenna array signal processing algorithms. The first one is the least-squares despread respread multitarget array (LSDRMTA) which utilizes the information of the spreading signals of different users in a CDMA system to adapt the weight vectors of a multitarget beamformer. The second one is the least-squares despread respread multitarget constant modulus algorithm (LSDRMTCMA) which combines the information of the spreading signal and the constant modulus property of the transmitted signal in the adaptation of the weight vectors.
