AN IMPROVED PREDICTION OF DCT-BASED IMAGE FILTERS EFFICIENCY USING REGRESSION ANALYSIS
Information and Telecommunication Sciences, 2014 Efficiency of DCT-based filters for a wide-class of images is investigated. The study is carried out for additive white Gaussian noise (AWGN) case with several intensity levels. Local DCT-based filter is used as basic denoising technique.

Robust quaternary fountain codes in AWGN interference
IET Communications, 2018 Luby transform (LT) codes have received less attention in larger non‐binary fields. Robust soliton distribution (RSD) was designed to provide universal optimality over the binary erasure channel in terms of minimising the overhead.

Modified CC-PEG Algorithm for Protograph-Based QC-LDPC Codes Over Non-Uniform Channel
IEEE AccessIn this paper, we propose the modified cycle-concentrating progressive-edge-growth (CC-PEG) algorithm for lifting protograph-based quasi-cyclic low-density parity-check (QC-LDPC) codes over the non-uniform additive white Gaussian noise (AWGN) channel. By

Anti-frequency-shift packet detection for D2D power-saving communications over Wi-Fi network
Tongxin xuebao, 2016 An efficient packet detection scheme based on Wi-Fi interface was proposed.It was implemented by employing a novel normalized factor as a denominator in OFDM symbol synchronization-timing metric.Compared to the old-tradition schemes,the proposed scheme ...

Guangtongxin yanjiu, 2007 文章首先介绍了跳时超宽带（TH-UWB）信号,推导了在加性高斯白噪声（AWGN）信道条件和多径条件（MP）下,基于重叠和正交脉冲信号的系统误码率公式,并给出了仿真结果。仿真结果表明,在AWGN信道条件下,基于重叠脉冲信号的跳时二进制脉位调制（TH-BPPM）系统的性能优于基于正交脉冲信号的系统。多径条件下的正交TH-BPPM系统的性能优于AWGN信道条件下的系统性能。

Revisit the AWGN-goodness of Polar-like Lattices
CoRRThis paper aims to provide a comprehensive introduction to lattices constructed based on polar-like codes and demonstrate some of their key properties, such as AWGN goodness. We first present polar lattices directly from the perspective of their generator matrix.

On the designand performance of nonbinary LDPC codes on burst errorchannels
Tongxin xuebao, 2013 Taking structured Q -ary irregular repeat-accumulate (S-QIRA) codes as an example, the burst-error-correcting capability of QLDPC codes was analyzed preliminarily by comparison with the burst-error-correcting capability of binary LDPC codes (BLDPC)and ...
