We develop a fast adaptive scheme of distortion management to reduce the overall distortion received by all users subject, to the limited number of codes and maximal transmitted power. Compared with a modified greedy method in literature, our proposed algorithm can reduce the overall system's distortion by at least 45%. %B Communications, 2004 IEEE International Conference on %V 5 %P 3071 - 3075 Vol.5 - 3071 - 3075 Vol.5 %8 2004/06// %G eng %R 10.1109/ICC.2004.1313096
