| Popis: | In this paper, we propose an enhanced ARQ scheme for OFDM systems exploit ing frequency and signal space diversities through subcarrier reassignment (SR) and constellation rearrangement (CR), respectively. The proposed SR scheme utilizes the channel state information to exploit frequency selectivity of the chan nel more effectively than the cyclic subcarrier shift based SR. Additionally, CR schemes may he used to improve the reliability of reception further. |
