Abstract

We propose a novel adaptive interleaving scheme for orthogonal frequency division multiplexing (OFDM) systems. Based on the channel state information, the approach selects one interleaver from a pool of candidate interleavers. As the selected one is expected to have larger minimum Euclidean distance (MED) at receiver, the technique can significantly improve the decoding error rate performance. Compared with the adaptive interleaving schemes proposed in literatures, the proposed scheme has no interleaving pattern synchronization problem and requires only a few bits for the signaling.
