Considering the power control optimum algorithm presented in the previous work for the uplink channel in the cooperative wireless CDMA network was highcomplexity

a new twophase lowcomplexity power control strategy and optimum algorithm is presented here. In the two phases

the distributed and geometricprogrammingbased power control optimum algorithms are applied respectively. The theoretic analysis and numerical simulation results show that the power control optimum algorithm presented in this paper has less channel information requirement

low computational complexity and fast convergence rate

and it can obtain the global optimal solution.
