Successive Wyner-Ziv Coding for the Binary CEO Problem under Logarithmic Loss
Mahdi Nangir, Reza Asvadi, Jun Chen +2
The -link binary Chief Executive Officer (CEO) problem under logarithmic loss is investigated in this paper. A quantization splitting technique is applied to convert the problem…
Successive Wyner-Ziv Coding for the Binary CEO Problem under Log-Loss
Mahdi Nangir, Reza Asvadi, Mahmoud Ahmadian-Attari +1
An -link binary CEO problem is considered in this paper. We present a practical encoding and decoding scheme for this problem employing the graph-based codes. A successive codin…
LDPC Codes over Gaussian Multiple Access Wiretap Channel
Sahar Shahbaz, Bahareh Akhbari, Reza Asvadi
We study the problem of two-user Gaussian multiple access channel (GMAC) in the presence of an external eavesdropper. In this problem, an eavesdropper receives a signal with a lowe…
Binary CEO Problem under Log-Loss with BSC Test-Channel Model
Mahdi Nangir, Reza Asvadi, Mahmoud Ahmadian-Attari +1
In this paper, we propose an efficient coding scheme for the two-link binary Chief Executive Officer (CEO) problem under logarithmic loss criterion. The exact rate-distortion bound…
Analysis and Code Design for the Binary CEO Problem under Logarithmic Loss
Mahdi Nangir, Reza Asvadi, Mahmoud Ahmadian-Attari +1
In this paper, we propose an efficient coding scheme for the binary Chief Executive Officer (CEO) problem under logarithmic loss criterion. Courtade and Weissman obtained the exact…
A Binary Wyner-Ziv Code Design Based on Compound LDGM-LDPC Structures
Mahdi Nangir, Mahmoud Ahmadian-Attari, Reza Asvadi
In this paper, a practical coding scheme is designed for the binary Wyner-Ziv (WZ) problem by using nested low-density generator-matrix (LDGM) and low-density parity-check (LDPC) c…
