| Abstract(in English) | This paper proposes a maximal ratio combining(MRC)frequency diversity automaticrepeat-request(ARQ)scheme which is suitable for high-speed orthogonal frequency division multiplexing(OFDM)systems. The proposed scheme regularly changes the subcarrier assignment pattern at each retransmission. This scheme sharply reduces the number of ARQ retransmissions in slow fading environments by virtue of the frequency diversity effect. Computer simulation results show that the proposed scheme reduces the number of retransmissions to about 4 at the accumulative correct packet reception rate(ACPRR)of 0.98. |
