Performance of Iterative Soft Output Viterbi Algorithm (SOVA) Decoder on Turbo Coding under Fading Channel
Classical turbo coding base on Parallel Concatenated Convolutional Code has been used for forward error correcting (FEC). From some research reports [1,2,3,5] this technique show new hope to get the coding technique at near Shanon limitation. This paper explains how SOVA decoder works on classical turbo coding. Performance analysis of SOVA decoder is observed by measure the number of bit error ...
متن کاملFast soft-output Viterbi decoding for duo-binary turbo codes
In this article, we describe the implementation of a Soft-Output Viterbi Decoder for an eight-state duo-binary code. This decoder is to be used in a turbo-decoder for convolutional codes. The implementation was made with the Synopsys environment and targeted a 0.18 m technology. The layout obtained has a working frequency of 150 MHz and thus an output data rate of 300 Mbits/s.
متن کاملHigh-Performance, Nondiffusive Crosslinked Polymers for Holographic Data Storage
Research into the development of new data-storage strategies is fueled by the continuing demand for ultrahigh information capacity, increased data density, smaller form factor, and faster readout rates. Conventional data-storage devices such as magnetic hard-disk drives, optical disks, and semiconductor memories all rely on storing information bit by bit on the surface of a recording medium. Ho...
متن کاملA Soft-Input Soft-Output Target Detection Algorithm for Passive Radar
Abstract: This paper proposes a novel scheme for multi-static passive radar processing, based on soft-input soft-output processing and Bayesian sparse estimation. In this scheme, each receiver estimates the probability of target presence based on its received signal and the prior information received from a central processor. The resulting posterior target probabilities are transmitted to the c...
متن کاملDesign of Soft Viterbi Algorithm Decoder Enhanced With Non-Transmittable Codewords for Storage Media
Viterbi Algorithm Decoder Enhanced with Non-transmittable Codewords is one of the best decoding algorithm which effectively improves forward error correction performance. HoweverViterbi decoder enhanced with NTCs is not yet designed to work in storage media devices. Currently Reed Solomon (RS) Algorithm is almost the dominant algorithm used in correcting error in storage media. Conversely, rece...
