Hsu–Kasami–Chien (HKC) codes are a class of cyclic codes that can correct either burst or random errors. This letter studies the maximum burst-correcting capability of HKC codes. A necessary and sufficient condition for a $b$ -burst-correcting cyclic HKC code is given and simplified as a generalized one for Fire codes. An upper bound on the burst-correcting capability of HKC codes is derived, which...
Incremental Attribute Learning (IAL) is a feasible machine learning strategy for solving high-dimensional pattern classification problems. It gradually trains features one by one, which is quite different from those conventional machine learning approaches where features are trained in one batch. Preprocessing, such as feature selection, feature ordering and feature extraction, has been verified as...
Fire codes are the most well-known class of burst-correcting codes. They are designed to correct bursts up to a given guaranteed burst-correcting capability. However, they may be able to correct longer bursts. In this paper, the true burst-correcting capability of Fire codes is studied. Fire codes are classified based on their parameters and the maximum true burst-correcting capability of each class...
Like the previous video coding standard, DCT and quantization are also adopted in HEVC. Compared with H.264/AVC, HEVC employs larger transform blocks, which makes the all zero block detection algorithm designed for H.264/AVC inefficient for HEVC. An efficient all zero block detection algorithm aimed at HEVC, especially for 16×16 and 32×32 transform blocks, is proposed in this paper based on frequency...
Forward Error Correction (FEC) consumes excessive computation in a Software Defined Radio (SDR) system. In this work, a high-throughput flexible FEC processor is proposed for the decoding acceleration. The FEC processor enables Turbo/QC-LDPC/Convolutional Code decoding with software-hardware co-reconfigurability. A multi-algorithm unified trellis processing unit is introduced for resource sharing...

Analysis the structure and working principle of the open source portal platform-Liferay Portal, the standards and models of Web components Portlet. And the design the structure of the model, using Liferay binding model developed digital learning platform successfully. The practical application...
In the precise phase difference measurement, we developed the dual phase coincidence detection method combined with a common oscillator. There is a certain frequency difference between the common oscillator and the two standard frequency signals which have the same nominal frequency. Utilizing the phase coincidence detection and a suitable processing, the time interval with the phase difference information...
In recent years, chaos-based image encryption technology has been extensively studied to meet the increasing demand for online secure image transmission over open networks. However, many of them suffer from known/chosen plaintext attacks as the diffusion key stream used in those schemes is solely determined by the key. To address this problem, a plaintext-related diffusion strategy is presented in...
Intra prediction with fine directions is a critical feature in the new High Efficiency Video Coding (HEVC) standard because it provides significant performance gain. Different from the intra prediction in the H.264/AVC, this approach is more complicated in terms of computation and memory access, which makes the VLSI design very difficult. In this paper, with the analysis of the algorithm of the DC...

This paper gives an analysis of current engineering programs, the reengineering effort of computer engineering programs and the CDIO Model, describes a new refined program based...
The key issue of packaged Low noise transistor noise parameter characterization is test fixture, this paper describes how to design test fixture and TRL cal standard based on PCB in detail, and also comprehensive verification of test fixture and TRL cal standard in frequency domain and time domain. What's more, this paper takes advantage of a new ultra-fast noise parameter measurement method with...
For higher phase lock precision, a new principle, the equivalent phase comparison frequency (EPCF) between signals in different frequencies, is presented in this paper. Using the new PLL based on EPCF, higher phase comparison and phase lock precision can be achieved with simple electrical circuits. Evidently, this principle is based on the analysis of time and phase, rather than on frequency simply...
