Robust and efficient video/image transmission
… demanding nowadays. Three aspects of this task, error burst correction, efficient rate allocation and random error protection are investigated in this dissertation. A novel technique, called successive packing, is proposed for combating multi-dimensional (M-D) bursts of errors. A new concept of …

An adaptive and reliable forward error correction mechanism for real-time video delivery from UAVs
… introduces the Adaptive and Reliable Forward Error Correction (AR-FEC) mechanism, an advanced protocol designed to enhance real-time video transmission in Unmanned Aerial Vehicles (UAVs) communications. Addressing the challenge of unreliable wireless channels, AR-FEC leverages edge computing …

Rateless and rateless unequal error protection codes for Gaussian channels
… different rateless codes and create a rateless unequal error protection code, all for the additive white Gaussian noise (AWGN) channel. The two rateless codes are examined through both analysis and simulation with the hope of developing a better understanding of how the codes will perform and …

Joint source channel coding for progressive image transmission
… streams are very sensitive to channel noise and protections from channel coding are necessary. Typical error correcting capability of channel codes varies according to different channel conditions. Thus, separate design leads to performance degradation relative to what could be achieved through …

Design Of Fountain Codes With Error Control
This thesis is focused on providing unequal error protection (uep) to two disjoint sources which are communicating to a comdestination via a comrelay by using distributed lt codes over a binary erasure channel (bec), and designing fountain codes with error control property by integrating lt codes …

Unequal Error Protection Raptor Codes
We design Unequal Error Protection (UEP) Raptor codes with the UEP property provided by the precode part of Raptor codes which is usually a Low Density Parity Check (LDPC) code. Existing UEP Raptor codes apply the UEP property on the Luby transform (LT) code part of Raptor codes. This approach …

Design and Implementation of An Emulation Testbed for Video Communications in Ad Hoc Networks
… 3. A modified H.263+ video codec that employs Unequal Error Protection (UEP) approach to generate MD video; 4. Implementation of three experiments that • compared the GA-based routing with existing technologies (NetMeeting video conferencing plus AODV routing); • compared our GA-based routing …

multimedia transmission over wireless networks: performance analysis and optimal resource allocation
… multimedia transmissions is analyzed. Unequal error protection (UEP) of data transmission using hierarchical quadrature amplitude modulation (HQAM) is considered in which high priority (HP) data is protected more than low priority (LP) data. In this setting, two different types of …

Low-bit-rate joint source-channel decoding aided wireless video communications
… Initially, we investigated the H.264 codec’s error sensitivity. The perceptually more important bits were provided with more strong protection relative to less important bits using Unequal Error Protection (UEP) by applying different-rate Recursive Systematic Convolutional (RSC) …

Wireless speech and audio communications
… Source and Channel Coding (JSCC) schemes, namely Unequal Error Protection (UEP) aided turbo transceivers as well as Iterative Source and Channel Decoding (ISCD) exploiting the residual redundancy inherent in the source encoded parameters.<br/>More specifically, in Chapter 2, two different UEP JSCC …
