Design of UEP-based MSE-minimizing rateless codes for source-channel coding
This paper proposes a method to optimize the performance of tandem source–channel coding with respect to the mean-squared error by exploiting the unequal error protection coding...

Wireless Video Transmission: A Single Layer Distortion Optimal Approach
In this paper, we introduce an analytical expression for the expected distortion of a single layer encoded video bit-stream. Based on the expected distortion model, we propose a d...

Exploiting UEP in QAM-based BICM: interleaver and code design
In this paper we formally analyze the interleaver and code design for QAM-based BICM transmissions using the binary reflected Gray code. We develop analytical bounds on the bit e...

LDPC FEC code extension for unequal error protection in 2nd generation DVB systems
One of the envisioned advantages of scalable video coding is its inherent suitability for achieving unequal error protection (UEP). UEP can be effectively used for graceful qualit...

Differential diversity-embedding space-time block coding for 2 and 4 transmit antennas
Diversity-Embedding Space-Time Block Coding (DE-STBC), introduced in [1], enables Unequal Error Protection (UEP) using multiple transmit antennas. Even though these codes do not re...

A Reduced-PAR Opportunistic STBC Scheme for Frequency-Selective Channels in the Presence of Frequency Offset
Opportunistic space-time block codes (STBC) have been investigated for flat-fading channels in the literature. In this paper, we present a novel scheme for integrating them with or...
