Implementation Of Fast rate Power Allocation Utilizing Duality gap in OFDM Systems
Journal Title: International Journal of Research in Computer and Communication Technology - Year 2012, Vol 1, Issue 5
Abstract
In this letter, we propose a power allocation strategy for orthogonal frequency division multiplexing (OFDM) systems. To achieve the maximum capacity, the proposed power allocation strategy iteratively tunes the amount of power allocated to subcarriers according to the related parameters in the duality gap. The proposed strategy has a fast rate to achieve the solution and a very low complexity, and it achieves almost optimum performance.
