| Abstract(in English) | In the next generation mobile communication systems, high speed and high capacity data services are demanded. However, unacceptable large transmit power may be required. Cooperative relay is known as one of the solutions for such a transmit power problem. In this paper, we investigate the uplink channel capacity of the single carrier -frequency division multiple access (SC-FDMA) with cooperative relay. To obtain increased frequency diversity gain, an adaptive subcarrier allocation using the spectral division and the channel state information is promising. However, the adaptive subcarrier allocation has a problem in increased peak-to-average power ratio (PAPR). The tradeoff between the channel capacity and the PAPR is discussed. |
