Kertas ini mencadangkan skim geganti berbilang pengguna yang cekap dalam sistem OFDMA. Dalam skim yang dicadangkan, berbilang terminal menghantar paket data mereka secara serentak dalam subjalur yang sama dan berbilang stesen geganti menghantar semula isyarat yang diterima dalam subjalur berbeza selepas penukaran subjalur. Stesen pangkalan (BS) mengekstrak paket individu daripada isyarat yang diterima dalam subband yang berbeza. Sebelum penghantaran data, BS memilih terminal yang sesuai supaya BS boleh mengekstrak paket data individu dengan jayanya. Keputusan berangka menunjukkan bahawa skim geganti yang dicadangkan mencapai daya tampung sistem yang lebih tinggi daripada skim geganti konvensional apabila penjadualan digunakan pada bilangan terminal yang lebih besar daripada bilangan stesen geganti.

Abstract: This paper proposes an efficient multiuser relay scheme in OFDMA systems. In the proposed scheme, multiple terminals transmit their data packets simultaneously in the same subband and multiple relay stations retransmit their received signals in different subbands after subband conversion. A base station (BS) extracts individual packets from received signals in the different subbands. In advance of data transmission, the BS selects appropriate terminals so that the BS can extract individual data packets successfully. Numerical results show that the proposed relay scheme achieves higher system throughput than the conventional relay scheme when scheduling is applied to a larger number of terminals than the number of relay stations.
