Error-resilient performance of dirac video codec over packet-erasure channel [PDF]

, 2007
Video transmission over the wireless or wired network requires error-resilient mechanism since compressed video bitstreams are sensitive to transmission errors because of the use of predictive coding and variable length coding.

Hybrid Adaptive Video Steganography Scheme Under Game Model

IEEE Access, 2019
The steganographic model based on game theory is improved. A hybrid steganography model that satisfies the Kerckhoffs principle by combining the strategy adaptation of the game theory model and the content adaptation in the cover model is proposed.

Error concealment for slice group based multiple description video coding [PDF]

, 2005
This paper develops error concealment methods for multiple description video coding (MDC) in order to adapt to error prone packet networks. The three-loop slice group MDC approach of D. Wang et al. (2005) is used.

Error probability and capacity analysis of generalised pre-coding aided spatial modulation [PDF]

, 2015
The recently proposed multiple input multiple output (MIMO) transmission scheme termed as generalized pre-coding aided spatial modulation (GPSM) is analyzed, where the key idea is that a particular subset of receive antennas is activated and the specific

Subset Vector Perturbation Pre-Coding for MU-MIMO Downlink Systems

IEEE Access, 2018
Multi-user multiple input multiple output (MU-MIMO) is a basic technique which has been widely investigated for its ability to increase system capacity. However, the inter-user interference (IUI) is one of the obstacles to obtain system capacity.

Randomly select and forward : Erasure probability analysis of a probabilistic relay channel model [PDF]

, 2009
This paper proposes a semi-analytical framework for estimating the erasure probability in single-hop multi-relay networks. Specifically, we consider a system, in which relays do not decode the information but simply forward coded packets that have been ...
