Abstract :
A neural network based multiuser detector for DS-CDMA systems is presented. By using the minimum output energy criterion, the detector is formulated as a constrained optimization problem and is then resolved efficiently by using neural network. The computational complexity of the proposed detector is only O(N), making its real-time implementation possible. It is shown that the proposed method is superior in computational efficiency to the conventional CRLS blind algorithm
