In this paper, we propose a new class of quasi-cyclic low-density parity-check (QC-LDPC) codes, namely cyclically-coupled QC-LDPC (CC-QC-LDPC) codes, and their RAM-based decoder architecture. CC-QC-LDPC codes have a simple structure and are construct

This paper investigates the puncturing pattern design of Hadamard codes. When designing the puncturing patterns, the minimum Hamming distance property and cross-correlation property of the punctured Hadamard codes are considered. The theoretical uppe

The bit mapping pattern has a crucial effect on the error performance of a bit-interleaved polar-coded modulation (BIPCM) system. In this paper, we have shown that a large proportion of the mapping patterns are producing the same error performances a

Recently, it has been found that the degree distribution of a user network has a significant effect on the traffic carried by a telephone network. In this paper, we investigate the effect of user clustering on the telephone traffic based on computer

This paper propose a decoder architecture for low-density parity-check convolutional code (LDPCCC). Specifically, the LDPCCC is derived from a quasi-cyclic (QC) LDPC block code. By making use of the quasi-cyclic structure, the proposed LDPCCC decoder

The performance of a high-throughput long-distance communication system such as an optical transmission system is limited by the Net Coding Gain (NCG) of the Forward Error Correction (FEC) system. Summarizing the previous research works, Low-Density

In this work, we propose an efficient quasi-cyclic LDPC (QCLDPC) decoder simulatorwhich runs on graphics processing units(GPUs). We optimize the data structures of the messages used in the decoding process such that both the read and write processes

In the traditional study of mobile cellular systems, all users are assumed to have the same behavior. They have the same probability of making/receiving a call and they will move around the network with identical mobility. In a practical environment,
