In TDMA digital transmission for use in portable indoor mdiocommunications,oneof the impairmentsencountered is correlated slow fading. At low pomble speeds typical of slow user mobility in the indoor communications, the frequency and duntion of e m r bursts due to deep fades influence the choice of the Forward Error Correction scheme to be used. FUI is effective against Rayleigh fading only whe...

We discuss the use of interleaving as a bandwidth efficient means of protecting audio streams from the effects of packet loss in the Internet. The adverse effects of interleaving on IP/UDP/RTP header compression are noted and a number of schemes which remedy this problem are discussed. Keywords— RTP, Interleaving, Voice-over-IP, header compression.

Regular Expressions (REs) form the basis of most XML type languages, such as DTDs, XML Schema types, and XDuce types (Thompson et al. 2004; Hosoya and Pierce 2003). In this context, the interleaving operator would be a natural addition to the language of REs, as witnessed by the presence of limited forms of interleaving in XSD (the all group), Relax-NG, and SGML. Unfortunately, membership check...

Sustained memory bandwidth for a range of access patterns is a key to high-performance vector processing. Interleaving is a popular way of constructing a high-bandwidth memory system. However, for some access patterns conflicts reduce the bandwidth of a standard, low-order interleaved memory. To improve memory bandwidth for a wide range of access patterns, alternate interleaving schemes must be...

Abstract DS-CDMA with frequency domain minimum mean square error (MMSE) equalization can provide much better performance than that with rake combining in a frequency selective fading channel. Chip interleaving is a form of channel interleaving that improves the DS-CDMA performance by converting the channel into a highly time selective channel. When frequency domain equalization is used, the fre...

In a previous paper, we developed an algebraic theory of threads and multi-threads based on strategic interleaving. This theory includes a number of plausible interleaving strategies on thread vectors. The strategic interleaving of a thread vector constitutes a multi-thread. Several multi-threads may exist concurrently on a single host in a network, several host behaviors may exist concurrently...

In process algebras such as ACP, parallel processes are considered to be interleaved in an arbitrary way. In the case of multi-threading as found in contemporary programming languages, parallel processes are actually interleaved according to some interleaving strategy. Interleaving strategies are also known as process-scheduling policies. In many systems, for instance hardware/software systems,...

This paper proposes a novel area-efficient folded modified convolutional interleaving (FMCI) architecture for MAP decoder. The end to end delay of proposed FMCI requires only 2M. In addition, the number of latches can reduce to M-2. Hence the proposed FMCI architecture has lesser end to end delay and minimizes the number of latches usage as compare with block interleaving and convolutional inte...

We proposed a novel interleaving technique, namely ada,ptive interleaving, which can break the bursty channel errors more effectively than traditional block interleaving. This new scheme resequences the transmitted symbols adaptively according to the instantaneous subcarrier channel state information. In this way, the bursty errors introduced by the channel can be broken more effectively, thus ...
