| Abstract(in English) | In a wireless network, the signals transmitted from one sender to different users have independent channel fluctuation characteristics. The diversity that exists between users is called multiuser diversity (MUD) and can be exploited by the sender to enhance the capacity of wireless network. In a MUD/OFDMA, exploiting channel fluctuation diversity is in essence done by selecting the user with the strong subcarrier channels. The individual subcarrier selection for each user can achieve the best system performance but large side information is required. On the other hand, the subcarrier block selection achieves worse BER than that of individual subcarrier selection. This is because the selected block contains the poor channel subcarriers. To overcome this problem, in this paper, we propose the reinforced multiuser diversity using frequency symbol spreading (FSS) and adaptive subcarrier block selection for OFDMA system. |
