A Perspective of Multi‐Reflecting TOF MS
Mass Spectrometry Reviews, EarlyView.ABSTRACT Time‐of‐flight mass spectrometry (TOF MS) excels in rapid and high‐sensitivity analysis, making it a cornerstone of analytical chemistry. But as sample complexity explodes in omics studies, so does the need for higher resolving power to ensure accurate results.

Turbo Analog Error Correcting Codes Decodable By Linear Programming [PDF]
arXiv, 2009 In this paper we present a new Turbo analog error correcting coding scheme for real valued signals that are corrupted by impulsive noise. This Turbo code improves Donoho's deterministic construction by using a probabilistic approach. More specifically, our construction corrects more errors than the matrices of Donoho by allowing a vanishingly small ...

Medical Physics, EarlyView.Abstract Background Diffusion‐weighted (DW) turbo‐spin‐echo (TSE) imaging offers improved geometric fidelity compared to single‐shot echo‐planar‐imaging (EPI). However, it suffers from low signal‐to‐noise ratio (SNR) and prolonged acquisition times, thereby restricting its applications in diagnosis and MRI‐guided radiotherapy (MRgRT).

VLSI Architectures for WIMAX Channel Decoders [PDF]
arXiv, 2010 This chapter describes the main architectures proposed in the literature to implement the channel decoders required by the WiMax standard, namely convolutional codes, turbo codes (both block and convolutional) and LDPC. Then it shows a complete design of a convolutional turbo code encoder/decoder system for WiMax.

Permutation Polynomial Interleavers: An Algebraic-Geometric Perspective [PDF]
, 2006 An interleaver is a critical component for the channel coding performance of turbo codes. Algebraic constructions are important because they admit analytical designs and simple, practical hardware implementation. The spread factor of an interleaver is a common measure for turbo coding applications. Maximum-spread interleavers are interleavers

Analog decoding of product codes [PDF]
, 2002 Journal ArticleAbstract - A method is presented for analog softdecision decoding of block product codes (block turbo codes). Extrinsic information is exchanged as analog signals between component row and column decoders.

On quasi-cyclic interleavers for parallel turbo codes [PDF]
IEEE Transactions on Information Theory, IT-52, No 4 (2006) pp.
1732--1739., 2005 We present an interleaving scheme that yields quasi-cyclic turbo codes. We prove that randomly chosen members of this family yield with probability almost 1 turbo codes with asymptotically optimum minimum distance, i.e. growing as a logarithm of the interleaver size.

Turbocodes and their application in telecommunication systems [PDF]
, 2008 Tato diplomová práce se zabývá problematikou Turbokódů. Tyto kódy patří do skupiny samoopravných kódů, někdy též nazývaných jako dopředné korekční kódy nebo kanálové kódy. Práci lze tématicky rozdělit na dvě základní části.

Ber Analysis of Turbo Code Interleaver
, 2015 This paper presents a low complexity interleaver design that facilitates high throughput Turbo decoding required for next generation wireless systems. When a parallel decoder structure is considered, interleaver design is the most important issue.

Performance of Turbo-Codes with Some Proposed Interleaver Schemes
Al-Khawarizmi Engineering Journal, 2006 This paper describes a number of new interleaving strategies based on the golden section. The new interleavers are called golden relative prime interleavers, golden interleavers, and dithered golden interleavers. The latter two approaches involve sorting
