Interleaver design for turbo codes
The performance of a Turbo code with short block length depends critically on the interleaver design. There are two major criteria in the design of an interleaver: the distance spectrum of the code and the correlation between the information input data and the soft output of each decoder corresponding to its parity bits. This paper describes a new interleaver design for Turbo codes with short b...
متن کاملTurbo-roundabout use and design
The turbo-roundabout concept has recently emerged in the Netherlands as a viable alternative to conventional multilane roundabouts, aiming to solve a set of functional problems related to the weaving maneuvers in the entry and negotiation zones. Although this is a recent concept, the Dutch experience has been showing that it is an extremely efficient solution, mainly in terms of safety. In fact...
متن کاملSCADA network forensics of the PCCC protocol
Most SCADA devices have few built-in self-defence mechanisms, and tend to implicitly trust communications received over the network. Therefore, monitoring and forensic analysis of network traffic is a critical prerequisite for building an effective defense around SCADA units. In this work, we provide a comprehensive forensic analysis of network traffic generated by the PCCC(Programmable Control...
متن کاملNew Iterative (\turbo") Decoding Algorithms
Decoding with feedback or iterative decoding is an eecient, low-complexity means for \informa-tion handover" in any parallel or serial concate-nated coding scheme and in related applications. Invented twenty years ago, it has recently been payed considerable attention in the context of \Turbo Codes". Iterative decoding has been jus-tiied intuitively, but many question remain and perhaps will re...
متن کاملQuantizer Design for Turbo-code Channels
1 A preliminary version of this work has been presented in 1,2]. A more detailed version of this work is reported in 3]. Abstract A new method of combined source-channel coding using Turbo-code is presented. The corresponding system transmits a discrete time, continuous amplitude signal over an Additive White Gaussian Noise (AWGN) channel where a Turbo-code is used for error correction purposes...
