An Efficient Algorithm for Finding Dominant Trapping Sets of LDPC Codes
Mehdi Karimi, Amir H. Banihashemi
This paper presents an efficient algorithm for finding the dominant trapping sets of a low-density parity-check (LDPC) code. The algorithm can be used to estimate the error floor o…
Analysis of Overlapped Chunked Codes with Small Chunks over Line Networks
Anoosheh Heidarzadeh, Amir H. Banihashemi
To lower the complexity of network codes over packet line networks with arbitrary schedules, chunked codes (CC) and overlapped chunked codes (OCC) were proposed in earlier works. T…
Network Codes with Overlapping Chunks over Line Networks: A Case for Linear-Time Codes
Anoosheh Heidarzadeh, Amir H. Banihashemi
In this paper, the problem of designing network codes that are both communicationally and computationally efficient over packet line networks with worst-case schedules is considere…
Density Evolution Analysis of Node-Based Verification-Based Algorithms in Compressive Sensing
Yaser Eftekhari, Anoosheh Heidarzadeh, Amir H. Banihashemi +1
In this paper, we present a new approach for the analysis of iterative node-based verification-based (NB-VB) recovery algorithms in the context of compressive sensing. These algori…
LLR Approximation for Wireless Channels Based on Taylor Series and Its Application to BICM with LDPC Codes
Reza Asvadi, Amir H. Banihashemi, Mahmoud Ahmadian-Attari +1
A new approach for the approximation of the channel log-likelihood ratio (LLR) for wireless channels based on Taylor series is proposed. The approximation is applied to the uncorre…
Design of Finite-Length Irregular Protograph Codes with Low Error Floors over the Binary-Input AWGN Channel Using Cyclic Liftings
Reza Asvadi, Amir H. Banihashemi, Mahmoud Ahmadian-Attari
We propose a technique to design finite-length irregular low-density parity-check (LDPC) codes over the binary-input additive white Gaussian noise (AWGN) channel with good performa…
