Capacity Optimization by Using Cancellation-Error-Ascending Decoding Order in Multimedia CDMA Networks with Imperfect Successive Interference Cancellation

We study the influence of decoding order on the capacity of multimedia DS-CDMA system employing imperfect successive interference cancellation. We prove that the capacity is maximized by decoding users according to the ascending order of cancellation errors. We also prove that this capacity-optimal decoding order makes total residual interference minimum at the same time.
