Kertas kerja ini mencadangkan skim gabungan nisbah maksimum (MRC) kepelbagaian frekuensi automatik-permintaan berulang (ARQ) baharu yang sesuai untuk sistem pemultipleksan bahagian frekuensi ortogonal berkelajuan tinggi (OFDM) yang berdasarkan paket konvensional yang menggabungkan skema ARQ. Skim yang dicadangkan sentiasa menukar corak tugasan subcarrier yang disediakan sebelum ini pada setiap penghantaran semula mengikut bilangan penghantaran semula. Skim ini secara mendadak mengurangkan bilangan penghantaran semula ARQ dan banyak meningkatkan prestasi pemprosesan dalam persekitaran pudar perlahan berdasarkan kesan kepelbagaian frekuensi sementara ia tidak memerlukan operasi penyesuaian yang kompleks. Keputusan simulasi komputer menunjukkan bahawa skim yang dicadangkan mengurangkan bilangan penghantaran semula yang diperlukan kepada kira-kira 3 pada kadar penerimaan paket betul terkumpul (ACPRR) sebanyak 0.9.

Abstract: This paper proposes a new maximal ratio combining (MRC) frequency diversity automatic-repeat-request (ARQ) scheme suitable for high-speed orthogonal frequency division multiplexing (OFDM) systems that is based on the conventional packet combining ARQ scheme. The proposed scheme regularly changes the previously prepared subcarrier assignment pattern at each retransmission according to the number of retransmissions. This scheme sharply reduces the number of ARQ retransmissions and much improves the throughput performance in slow fading environments by virtue of the frequency diversity effect while it requires no complex adaptive operations. Computer simulation results show that the proposed scheme reduces the required number of retransmissions to about 3 at the accumulative correct packet reception rate (ACPRR) of 0.9.
