Abstract :
We investigate the behavior of the multi-carrier DS-CDMA (MC-DS-CDMA) synchronous systems based on linear detectors under different power assignment strategies in the presence of multiuser interference. We use algorithms that maximize the user throughput or minimize the bit error rate (BER). The effects of the number of nonorthogonal users, interference, channel attenuation and the used criteria are also investigated. Numerical results allow us to characterize the efficiency of the power assignment algorithms related to the implied detectors
