Joint design of QC-LDPC codes for coded cooperation system with joint iterative decoding

In this paper, we investigate joint design of quasi-cyclic low-density-parity-check (QC-LDPC) codes for coded cooperation system with joint iterative decoding in the destination. First, QC-LDPC codes based on the base matrix and exponent matrix are introduced, and then we describe two types of girth-4 cycles in QC-LDPC codes employed by the source and relay. In the equivalent parity-check matrix corresponding to the jointly designed QC-LDPC codes employed by the source and relay, all girth-4 cycles including both type I and type II are cancelled. Theoretical analysis and numerical simulations show that the jointly designed QC-LDPC coded cooperation well combines cooperation gain and channel coding gain, and outperforms the coded non-cooperation under the same conditions. Furthermore, the bit error rate performance of the coded cooperation employing jointly designed QC-LDPC codes is better than those of random LDPC codes and separately designed QC-LDPC codes over AWGN channels.     

A collaborating colleague model for inducting internationalengineering students into the language and culture of a foreign researchenvironment

Practitioners of research in a particular field have extensive knowledge of how to operate successfully in that field and communicate effectively with others, within the boundaries of their own language and culture. However, when it comes to inducting novice researchers into these skills, difficulties are often encountered, and more so when the novice comes from a different language and cultural background. At the same time, specialists in English teaching or cross-cultural communication aiming to prepare novices to enter such a research environment often lack access to the details of how things are really done there. At The University of Adelaide, South Australia, this situation is being addressed through a new program for international postgraduate students in their first semester of enrolment. This Integrated Bridging Program (IBP) relies on collaboration between the discipline specialist researcher and language and learning specialists and is informed by the perspectives of systemic functional linguistics (SFL). This paper presents an overview of the IBP, followed by details of its operation in the Faculty of Engineering. Information is included on outcomes of the collaboration in specific instances, and how SFL theory has been applied to develop a flexible and effective induction which is highly valued by both staff and student participants     

Exploring the design space of mixed swing quadrail for low-powerdigital circuits

This paper describes and explores the design space of a mixed voltage swing methodology for lowering the energy per switching operation of digital circuits in standard submicron complementary metal-oxide-semiconductor (CMOS) fabrication processes. Employing mixed voltage swings expands the degrees of freedom available in the power-delay optimization space of static CMOS circuits. In order to study this design space and evaluate the power-delay tradeoffs, analytical polynomial formulations for power and delay of mixed swing circuits are derived and HSPICE simulation results are presented to demonstrate their accuracy. Efficient voltage scaling and transistor sizing techniques based on our analytical formulations are proposed for optimizing energy/operation subject to target delay constraints; up to 2.2× improvement in energy/operation is demonstrated for an ISCAS'85 benchmark circuit using these techniques. Experimental results from HSPICE simulations and measurements from an And-Or-Invert (AO1222) test chip fabricated in the Hewlett-Packard 0.5 μm process are presented to demonstrate up to 2,92× energy/operation savings for optimized mixed swing circuits compared to static CMOS     

Exploring the design space of reliable multicast protocols for wireless mesh networks

Many important applications in wireless mesh networks require reliable multicast communication, i.e., with 100% packet delivery ratio (PDR). Previously, numerous multicast protocols based on automatic repeat request (ARQ) have been proposed to improve the packet delivery ratio. However, these ARQ-based protocols can lead to excessive control overhead and drastically reduced throughput. In this paper, we present a comprehensive exploration of the design space for developing high-throughput, reliable multicast protocols that achieve 100% PDR.Motivated by the fact that 802.11 MAC layer broadcast, which is used by most wireless multicast protocols, offers no reliability, we first examine if better hop-by-hop reliability provided by unicasting the packets at the MAC layer can help to achieve end-to-end multicast reliability. We then turn to end-to-end solutions at the transport layer. Previously, forward error correction (FEC) techniques have been proved effective for providing reliable multicast in the Internet, by avoiding the control packet implosion and scalability problems of ARQ-based protocols. In this paper, we examine if FEC techniques can be equally effective to support reliable multicast in wireless mesh networks. We integrate four representative reliable schemes (one ARQ, one FEC, and two hybrid) originally developed for the Internet with a representative multicast protocol ODMRP and evaluate their performance.Our experimental results via extensive simulations offer an in-depth understanding of the various choices in the design space. First, compared to broadcast-based unreliable ODMRP, using unicast for per-hop transmission only offers a very small improvement in reliability under low load, but fails to improve the reliability under high load due to the significantly increased capacity requirement which leads to congestion and packet drop. Second, at the transport layer, the use of pure FEC can significantly improve the reliability, increasing PDR up to 100% in many cases, but can be inefficient in terms of the number of redundant packets transmitted. In contrast, a carefully designed ARQ–FEC hybrid protocol, such as RMDP, can also offer 100% reliability while improving the efficiency by up to 38% compared to a pure FEC scheme. To our best knowledge, this is the first in-depth study of high-throughput, reliable multicast protocols that provide 100% PDR for wireless mesh networks.     

Effect of silicon-surface orientation in the bulk model of thermal oxidation

On the basis of the bulk model of thermal oxidation of silicon [O. V. Aleksandrov and A. I. Dusj, Semiconductors 41 (11), 1370 (2008)], the orientation dependence of the silicon’s oxidation rate in dry oxygen is analyzed. The orientation and temperature dependences of diffusivity in stressed silicon dioxide and its characteristic relaxation time are determined. The orientation dependence of the oxidizer diffusivity in silicon dioxide on the reaction-zone boundary, D ₁(110) > D ₁(111) > D ₁(100), is related to the orientation effect of the single-crystal silicon substrate on the structure and density of adjoining silicon dioxide. The orientation dependence of the characteristic relaxation time, τ(100) > τ(110) > τ(111), is inversely correlated with the orientation dependence of D ₁ for the (100) and (111) orientations and directly correlated with the internal stresses for the (110) and (111) orientations.
