Autoencoder-Based Unequal Error Protection Codes [PDF]
, 2021 We present a novel autoencoder-based approach for designing codes that provide unequal error protection (UEP) capabilities. The proposed approach, based on a generalization of an autoencoder loss function, provides a versatile framework for the design of

Distributed Rateless Codes with Unequal Error Protection Property for Space Information Networks
Entropy, 2017 In this paper, we propose a novel distributed unequal error protection (UEP) rateless coding scheme (DURC) for space information networks (SIN). We consider the multimedia data transmissions in a dual-hop SIN communication scenario, where multiple ...

Performance of Polar‐Coded 3D Image Transmission over Fading Channel
Mathematical Problems in Engineering, Volume 2020, Issue 1, 2020., 2020 Any signal transmitted over an air‐to‐ground channel is corrupted by fading, noise, and interference. In this paper, a Polar‐coded 3D point cloud image transmission system with fading channel is modeled, and also the simulation is performed to verify its performance in terms of 3D point cloud image data transmission over Rician channel with Gaussian ...

Wireless Communications and Mobile Computing, Volume 2020, Issue 1, 2020., 2020 In this research work, we have presented an iterative joint source channel decoding‐ (IJSCD‐) based wireless video communication system. The anticipated transmission system is using the sphere packing (SP) modulation assisted differential space‐time spreading (DSTS) multiple input‐multiple output (MIMO) scheme.

Video Prioritization for Unequal Error Protection [PDF]
, 2011 We analyze the effect of packet losses in video sequences and propose a lightweight Unequal Error Protection strategy which, by choosing which packet is discarded, reduces strongly the Mean Square Error of the received ...

Error-Resilient Unequal Error Protection of Fine Granularity Scalable Video Bitstreams
EURASIP Journal on Advances in Signal Processing, 2006 This paper deals with the optimal packet loss protection issue for streaming the fine granularity scalable (FGS) video bitstreams over IP networks. Unlike many other existing protection schemes, we develop an error-resilient unequal error protection (ER-
