Hierarchical Polar Coding for Achieving Secrecy over Fading Wiretap Channels without any Instantaneous CSI
Hongbo Si, O. Ozan Koyluoglu, Sriram Vishwanath
This paper presents a polar coding scheme to achieve secrecy in block fading binary symmetric wiretap channels without the knowledge of instantaneous channel state information (CSI…
A Novel and Efficient Vector Quantization Based CPRI Compression Algorithm
Hongbo Si, Boon Loong Ng, Md. Saifur Rahman +2
The future wireless network, such as Centralized Radio Access Network (C-RAN), will need to deliver data rate about 100 to 1000 times the current 4G technology. For C-RAN based net…
Expansion Coding for Channel and Source Coding
Hongbo Si, O. Ozan Koyluoglu, Kumar Appaiah +1
A general method of coding over expansion is proposed,which allows one to reduce the highly non-trivial problems of coding over analog channels and compressing analog sources to a…
Haplotype Assembly: An Information Theoretic View
Hongbo Si, Haris Vikalo, Sriram Vishwanath
This paper studies the haplotype assembly problem from an information theoretic perspective. A haplotype is a sequence of nucleotide bases on a chromosome, often conveniently repre…
Polar Coding for Fading Channels: Binary and Exponential Channel Cases
Hongbo Si, O. Ozan Koyluoglu, Sriram Vishwanath
This work presents a polar coding scheme for fading channels, focusing primarily on fading binary symmetric and additive exponential noise channels. For fading binary symmetric cha…
Lossy Compression of Exponential and Laplacian Sources using Expansion Coding
Hongbo Si, O. Ozan Koyluoglu, Sriram Vishwanath
A general method of source coding over expansion is proposed in this paper, which enables one to reduce the problem of compressing an analog (continuous-valued source) to a set of…
