Abstract:

An adaptive distributed power allocation (DPPA) algorithm based on potential games is proposed. Subband capacity with penalty factor is raised as the utility function. A global optimization could be transformed into a local optimization problem with iteration. By means of gradient projection, the power could be adaptively allocated, and the intercell interference is restrained. As a result, the intercell interference coordination and reduction of time price are achieved. It is shown that the algorithm reduced the capacity loss effectively, while increasing the throughputs for celledge users.

Key words: intercell interference, potential games, gradient projection, power allocation
