We propose a DPC-PA (Distributed Power Control with Power Assignment) algorithm to speed up the process of finding a feasible power set for multimedia CDMA wireless networks. We prove that given a feasible configuration, the power set of the DPC-PA algorithm will converge to a feasible power set which achieves equality in a set of linear equations. We also found, from numerical experiments, that the DPC-PA algorithm can find a feasible power set (if there is one) much faster than the distributed power control algorithm without power assignment.
