A parallel Viterbi decoding algorithm
Concurrency and Computation: Practice and Experience, 2001 AbstractIn this paper we express the Viterbi algorithm as a matrix–vector reduction in which multiplication is replaced by addition and addition by minimization. The resulting algorithm is then readily parallelized in a form suitable for implementation on a systolic processor array.

Unlocking Photodetection Mode Switching from a Simple Lateral Design
Advanced Functional Materials, EarlyView.A simple lateral 2D perovskite photodetector capable of switching among transient, continuous, and dual transient/continuous photoresponse modes is achieved by integrating photoconductive effects with capacitive coupling from the SiO2/Si substrate. Such light‐programmable photodetection mode switching enables triple‐channel information transmission and

A Fully-Parallel Turbo Decoding Algorithm [PDF]
IEEE Transactions on Communications, 2015 This paper proposes a novel alternative to the Logarithmic Bahl-Cocke-Jelinek-Raviv (Log-BCJR) algorithm for turbo decoding, yielding significantly improved processing throughput and latency. While the Log-BCJR processes turbo-encoded bits in a serial forwards-backwards manner, the proposed algorithm operates in a fully-parallel manner, processing all ...
