Study of Power Control Strategy and Optimum Algorithm for Uplink Channel in a Cooperative Wireless CDMA Network
Considering the power control optimum algorithm presented in the previous work for the uplink channel in the cooperative wireless CDMA network was highcomplexity
a new twophase lowcomplexity power control strategy and optimum algorithm is presented here. In the two phases
the distributed and geometricprogrammingbased 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.
