| Abstract(in English) | In this paper, we propose the resource allocation algorithm based on Nash Bargaining Solution (NBS) in single-carrier-frequency division multiple access (SC-FDMA). In SC-FDMA, system capacity can be improved by allocating a subcarrier to the user who obtains good channel gain. However, there is a tradeoff between system capacity and fairness among users. Game theory, especially NBS in cooperative game theory, can be used to solve the tradeoff. But generally, unacceptable computational complexity is required to find NBS. In this paper, we propose a sub-optimal NBS resource allocation method, which requires lower computational complexity while achieving almost the same performance as NBS. The proposed method is applied to distributed antenna network (DAN) with frequency domain space-time transmit diversity (FD-STTD) to further improve both system capacity and fairness among users. Numerical computation results show that the proposed method not only provide fair resource allocation but also keeps system capacity compared to both PF map method and Max map method. |
