“…Effects of both types of interference, namely ISI and IPI, are considered. Furthermore, we investigate the performance of previously proposed interleaved coding-modulation [13] applied in combination with superorthogonal convolutional (SOC) coding or frame repetition (FR). Tests are conducted in a multi-user scenario focusing on the design of time-hopping (TH)-like sequences that are used for chip interleaving.…”

Abstract-Interleaved coding-modulation (ICM) is a recently proposed method for ultra-wideband impulse radio (UWB-IR) systems. ICM exploits the concept of chip interleaving, allowing to alleviate the problem of inter-symbol and inter-pulse interference commonly present in high data rate UWB-IR systems. In this paper, previous work on ICM is extended to scarcely populated multi-user scenarios. A novel design of a deterministic chip interleaver based on time-hopping hyperbolic congruence sequences is proposed. Furthermore, the main parameters of the random and hyperbolic interleavers are reviewed. The obtained results indicate that the proposed type of interleaver yields similar performance to random interleavers but with the advantage of simpler implementation.

We propose a design of a deterministic chip interleaver based on time-hopping hyperbolic congruence sequences. We also review the main parameters of the random and hyperbolic interleavers. Our results indicate that the proposed type of interleaver yields similar performance to random interleavers but with the advantage of simpler implementation.
