멀티 유저 OFDM 시스템에서 QoS 보장을 위한 서브캐리어와 파워 할당에 관한 연구
A Sub-optimal Joint Subcarrier and Power Allocation Algorithm for Qos Supporting in Muliuser OFDM Systems
초록
This paper suggests that resource allocation algorithm in multiuser orthogonal frequncy divisioin multiplexing (OFDM). The proposed algorithm considers throughput maximization with power constraint and quality of service (QoS) constraint. This problem has a optimal solution with using well known water-filling algorithm but the algorithm requires high computational complexity. Therefore the problem needs a sub-optimal algorithm for decreasing computational complexity. We propose a sub-optimal joint subcarrier and power allocation algorithm for multiuser OFDM system and compare with previous resource allocation algorithm.
