| Abstract(in English) | In this paper, we propose a power allocation method that maximizes the uplink capacity of the cooperative amplify-and-forward (AF) relay using direct/cooperative relay switching and spectrum division/adaptive subcarrier allocation (SDASA). When the cooperative relay is selected, the proposed power allocation method adaptively allocates the transmit power between a mobile terminal (MT) and a relay station (RS) according to the conditions of MT-RS and RS-base station (BS) links. We show by computer simulation that the proposed power allocation method can achieve almost the same channel capacity as the greedy power allocation method. |
