| Abstract(in English) | This paper proposes an efficient multiuser relaying scheme in OFDMA systems. In the proposed scheme, multiple terminals transmit data streams simultaneously in the same subband and multiple relay stations amplify and forward their signals in different subbands after subband conversion. The base station (BS) extracts each data stream from mufti-dimensional signals received at the different subbands. In advance of the data transmission, the BS selects appropriate terminals whose data streams have semi-orthogonal signatures at the BS. Numerical results show that the proposed scheme achieves much higher system throughput than the conventional scheme. |
