Low-density parity-check codes using the beliefpropagation decoding algorithm tend to exhibit a high error floor in the bit error rate curves, when some problematic graphical stru...
Abstract— In this paper, we propose partly parallel architectures based on optimal overlapped sum-product (OSP) decoding. To ensure high throughput and hardware utilization effi...
Low-density parity-check (LDPC) codes on par with convolutional turbo codes (CTC) are two of the most powerful error correction codes known to perform very close to the Shannon li...
We propose a new graph representation for ISI channels that can be used for combined equalization and decoding by linear programming (LP) or iterative message-passing (IMP) decodi...
1 — The authors of this paper proposed an iterative expectation-maximization (EM) channel estimation based on a low-density parity-check (LDPC) code-division multiple access rece...
