Abstract :
A coordinated coding strategy for increasing the capacity of the forward-link in DS-CDMA is studied. The goal is to minimize the average error probability for a given value of the transmitted energy per bit. The transmitter (base station) estimates the mutual interference of the individual signals, and adjusts the transmitted signal in order to yield minimum average error probability. The algorithm is by computer simulations shown to result in substantial improvements both for the AWGN channel and the flat Rayleigh fading channel
