Based on perturbation theory, formulas for multi-user detection in CDMA systems are derived. Starting from single user detection and applying iterative perturbations to correct for interference, we obtain better linear combination amplitudes for codes of the multi-user waveform and hence lower bit error rate (BER). The computation complexity is reduced to the minimum by calculating the interference in frames and sliding 3-symbol-window for all users
