摘要：

We solve the power allocation problem for distributed antenna system (DAS) in [1] with a simple algorithm running in polynomial time. Simulations in two scenarios with single and three sectors per cell show that the proposed power allocation scheme in DAS achieves higher system capacity by 50.1%, and 45.9%, respectively, in comparison with macro base station. Our proposal provides a practical and cost effective solution to address the issues of deployment cost and system capacity.
