Jointly optimised iterative source-coding, channel-coding and modulation for transmission over wireless channels

, 2004
Joint source-coding, channel-coding and modulation schemes based on Variable Length Codes (VLCs), Trellis Coded Modulation (TCM), Turbo TCM (TTCM), Bit-Interleaved Coded Modulation (BICM) and iteratively decoded BICM (BICM-ID) schemes are proposed.

Joint Source-Channel Coding Using Variable-Length Error-Correcting Codes

Journal of Engineering and Sustainable Development, 2010
This paper explores the performance of both source coding and error-correction in a single coding step. Such joint source-channel coding is done here using codewords of varying lengths that have particular distance properties with each other, which ...

ADAPTATION OF JOINT SOURCE-CHANNEL CODING TO OPTIMIZE THE BANDWIDTH TRANSMISSION VOICE OVER LTE NETWORK

Telemática, 2020
In mobile communication systems over LTE, voice packets are transmitted over noisy channels that negatively affect the probability of losses. An important mechanism to combat packet loss is channel coding.

ChicGrasp: Imitation‐Learning‐Based Customized Dual‐Jaw Gripper Control for Manipulation of Delicate, Irregular Bio‐Products

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 ...

A Deep Variational Approach to Multiterminal Joint Source-Channel Coding Based on Information Bottleneck Principle

IEEE Open Journal of the Communications Society
In this article, we concentrate on a generic multiterminal joint source-channel coding scenario, appearing in a wide variety of real-world applications. Specifically, several noisy observations from a source signal must be compressed at some intermediate

Muscle Control of an Extra Robotic Digit

Advanced Robotics Research, EarlyView.
This study compares muscle‐ and movement‐based control for operating a supernumerary robotic thumb. While movement control performs better in the proposed tasks, muscle‐based (EMG) control promotes broader motor learning. The results highlight the promise and challenges of using biosignals for human augmentation, offering new insights into intuitive ...

A Multidirectional Textile Interface for Remote Control Using Dynamic Area‐Based Capacitance Modulation

Advanced Robotics Research, EarlyView.
Here, we present a textile, wearable capacitive interface enabling multidirectional remote control by dynamically modulating electrode overlap and spacing via a freely gliding upper electrode. A forearm‐mounted prototype drives robotic and media tasks with 12–15 ms latency, maintains < 0.8% drift after 500 cycles, and remains stably functional at 90 ...
