(English Abstract) |
Downlink SDMA/OFDMA system is widely used for high data rate wireless mobile communications due to high spectral efficiency and robustness to multipath distortion. This paper considers the resource allocation for throughput maximization in this system with multiuser environment. Previous allocation methods suggest iterative algorithm which requires high complexity, and they has not been applied in the system simulation. We propose the sub-optimal algorithm with lower complexity, and confirm the system simulation result over two systems; one is assigned users by user assignment set and allocated power for those users, and another is assigned full users and distributed power evenly.
