Abstract:

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

Key words: adaptive interleaving, orthogonal frequency division multiplexing, bit interleaved coded modulation
