  Abstract

In this paper. we studied on combining the control of transmission rates and power for the real system where a finite set of transmission rates are used. In [1], the combined control of transmission rates and power was first researched. and suggested the Selective Power Control (SPC) algorithm. However. it can't guarantee the minimum rate to each user and results in frequent changes of rate due to oscillation of the SIR (Signal to Interference Ratio) values. As a main purpose of this paper. we derive a formulation model and propose a distributed iteration algorithm to solve these problems. To evaluate the performance of the proposed algorithm. we carried out numerical analysis and computational experiments. The results indicate that the proposed algorithm achieves better throughput than conventional one by keeping the low average transmission power.
