Efficient Evaluation and Design of Interleaving Strategy for Communication Systems

Le résumé fourni par la source

To combat bursty errors caused by wireless channels, interleaving is usually employed to randomize these errors with an aim to make error correction codes more effective. Subsequently, the design of efficient interleaving strategies becomes an attractive topic. Our main contributions of this paper consist: i) put forward equivalent distance sum from the physical scenarios as the metric of an interleaving sequence, which can give an overall but meticulous characterization of interleaving; ii) combine unequal grouping strategy with group interleaving to exploit the potential of interleaving which mostly outperforms classical block interleaving; iii) develop a practical algorithm to generate the near-optimal interleaving sequence with arbitrary length based on underlying insights. Numerical results under IEEE 802.11aj (45 GHz) millimeter-wave system in single carrier mode validate the effectiveness of the algorithm.
