Research on unequal error protection of irregular LDPC codes

Tongxin xuebao, 2005
An irregular low-density parity-check （LDPC） code with unequal error protection （UEP） property was proposed. A weight-increasing parity-check （WIPC） matrix was constructed.

Real‐Time 3D Ultrasound Imaging with an Ultra‐Sparse, Low Power Architecture

Advanced Healthcare Materials, EarlyView.
This article presents a novel, ultra‐sparse ultrasound architecture that paves the way for wearable real‐time 3D imaging. By integrating a unique convolutional array with chirped data acquisition, the system achieves high‐resolution volumetric scans at a fraction of the power and hardware complexity.

Multilevel Block Coded Modulation with Unequal Error Protection [PDF]

, 1997
Multilevel block coded modulation (BCM) schemes with unequal error protection (UEP) are investigated. These schemes are based on unconventional set partitions that greatly reduce the error coefficients associated with multi-stage decoding of conventional

Adaptive UEP and Packet Size Assignment for Scalable Video Transmission over Burst-Error Channels

EURASIP Journal on Advances in Signal Processing, 2006
This work proposes an adaptive unequal error protection (UEP) and packet size assignment scheme for scalable video transmission over a burst-error channel. An analytic model is developed to evaluate the impact of channel bit error rate on the quality of

Unequal Error Protection Querying Policies for the Noisy 20 Questions Problem

, 2017
In this paper, we propose an open-loop unequal-error-protection querying policy based on superposition coding for the noisy 20 questions problem. In this problem, a player wishes to successively refine an estimate of the value of a continuous random ...
