A Global Optimization Algorithm for Power Allocation of a Wireless Communication System
Transmitted-power allocation (TPA) is essential for minimizing power consumption and managing interference in many wireless communication systems. In this paper, we study a TPA problem for systems with interleave-division multiple-access (IDMA) and with a finite number of transmitted-power levels. The tPA problem has been tackled in our previous work by transforming the original formulation into a linear zero-one programming (LZOP) form. This approach could efficiently obtain good feasible points of the TPa problem, it nevertheless does not guarantee to obtain the optimal ones. In this paper, we devise an algoritlun that guarantees to obtain solutions of the tPA problem. The idea is to iteratively refine a good feasible point, which is obtained by solving the above-mentioned LZOP problem, until a solution of the tPA problem is obtained. We demonstrate the efficiency of the proposed algorithm by numerical examples.
