Features of the iSCSI Protocol
The iSCSI protocol specifies how to access SCSI storage devices over a TCP network. The authors give a brief introduction to the iSCSI protocol and a brief comparison with alternative technologies.

Performance Study of iSCSI-Based Storage Subsystems
iSCSI is emerging as an end-to-end protocol for transporting storage I/O block data over IP networks. By exploiting the ubiquitous Internet infrastructure, iSCSI greatly facilitates remote storage, remote backup, and data mirroring.
Yingping Lu and David H. C. Du, University of Minnesota
The authors describe object-based storage, stressing how it improves data sharing, security, and device intelligence. They also discuss some industry applications of object-based storage and academic research using objects as a foundation for building even more intelligent storage systems.
Mike Mesnier, Carnegie Mellon and Intel; Gregory R. Ganger, Carnegie Mellon; Erik Riedel, Seagate ResearchSecure Group Key Management for Storage Area Networks
Storage area networks offer high availability, reliability, and scalability, and are a promising solution for large-scale storage needs of many enterprises. As with any distributed storage system, a major design challenge for SANs is to provide secure storage, which implies data integrity and data confidentiality.

Capacity Approaching Codes, Iterative Decoding Algorithms, and Their Applications |

Concatenated Convolutional Codes with Interleavers
The authors present a tutorial overview of the class of concatenated convolutional codes with interleavers, also known as turbo-like codes.
Sergio Benedetto and Guido Montorsi, CERCOM — Politecnico di Torino; Dariush Divsalar, Sequoia Communications
In the matter of channel coding and spectral efficiency, up to the invention of turbo codes, 3 dB or more stood between what the theory promised and what real systems were able to offer. This gap has now been removed.
Claude Berrou, ENST BretagneCodes Defined on Graphs
Low-density parity-check codes, turbo codes, and indeed most practically decodable capacity-approaching error correcting codes can all be understood as codes defined on graphs.
Frank R. Kschischang, University of TorontoThe Renaissance of Gallager's Low-Density Parity-Check Codes
LDPC codes were invented in 1960 by R. Gallager. They were largely ignored until the discovery of turbo codes in 1993. Since then, LDPC codes have experienced a renaissance and are now one of the most intensely studied areas in coding.
Tom Richardson, Flarion Technologies; Rüdiger Urbanke, EPFL
The authors investigate implementation constraints on iterative decoders applying message-passing algorithms.

RF CMOS Transceivers for Cellular Telephony
The author describes system and circuit issues related to cellular transceivers, with design techniques that have provided high performance in CMOS technology.
Behzad Razavi, University of CaliforniaIntegrated Circuits for Channel Coding in 3G Cellular Mobile Wireless Systems
Error control coding is a key element of any digital wireless communication system, minimizing the effects of noise and interference on the transmitted signal at the physical layer.
Charles Thomas, Mark A. Bickerstaff, Linda M. Davis, Thomas Prokop, Ben Widdup, Gongyu Zhou, David Garrett, and Chris Nicol, Bell Laboratories, Lucent Technologies AustraliaDesign and Implementation of an All-CMOS 802.11a Wireless LAN Chipset
The tremendous growth in wireless LANs has generated interest in technologies that provide higher data rates and greater system capacities. The IEEE 802.11a standard provides nearly five times the data rate and at least 20 times the overall system capacity compared to the incumbent 802.11b wireless LAN systems.
