THE EFFECT OF TRELLIS TERMINATION ON THE PERFORMANCE OF TURBO CODE
Journal of Engineering, 2003 This paper introduces a new class of convolutional codes, which is called Turbo Code. Turbo Code was shown to achieve performance in terms of Bit-Error-Rate (BER), which is near Shannon limit.

Information Transmission Strategies for Self‐Organized Robotic Aggregation
Advanced Robotics Research, EarlyView.In this review, we discuss how information transmission influences the neighbor‐based self‐organized aggregation of swarm robots. We focus specifically on local interactions regarding information transfer and categorize previous studies based on the functions of the information exchanged.

Iterative Syndrome-Based Deep Neural Network Decoding
IEEE Open Journal of the Communications SocietyWhile the application of deep neural networks (DNNs) for channel decoding is a well-researched topic, most studies focus on hard output decoding, potentially restricting the practical application of such decoders in real communication systems.

Unequal Error Protection Irregular Over-Complete Mapping for Wavelet Coded Wireless Video Telephony Using Iterative Source and Channel Decoding [PDF]
, 2008 —Since the different bits of the compressed video sequence produced by the BBC’s wavelet-based video codec exhibit different error sensitivity, efficient Unequal Error Protection (UEP) schemes have to be used to ensure that the perceptually more ...

Advanced Robotics Research, EarlyView.Visual teach‐and‐repeat (VTR) navigation allows robots to learn and follow routes without building a full metric map. We show that navigation accuracy for VTR can be improved by integrating a topological map with error‐drift correction based on stereo vision.

Turbo codes and turbo algorithms
Journal of Communications Software and Systems, 2006 In the first part of this paper, several basic ideas that prompted the coming of turbo codes are commented on. We then present some personal points of view on the main advances obtained in past years on turbo coding and decoding such as the circular ...

Partial IDS decoding based on the base graph of protograph LDPC codes
IET Communications, 2023 The residual belief propagation (RBP) algorithm, which is the most classic informed dynamic scheduling strategy, achieves outstanding performance in error correction and can drastically accelerate convergence speed.

Three-Dimensional EXIT Chart Analysis of Iterative Detection Aided Coded Modulation Schemes [PDF]
, 2006 The iterative convergence of iteratively detected coded modulation schemes having different block lengths, decoding complexity and an unequal error protection capability is studied, when communicating over AWGNchannels using 8PSK modulation.

Advanced Robotics Research, EarlyView.Automated poultry processing lines still rely on humans to lift slippery, easily bruised carcasses onto a shackle conveyor. Deformability, anatomical variance, and hygiene rules make conventional suction and scripted motions unreliable. We present ChicGrasp, an end‐to‐end hardware‐software co‐designed imitation learning framework, to offer a ...
