Concatenated coding schemes with interleavers consist of a combination of two simple constituent encoders and an interleaver. The parallel concatenation known as "turbo code" has been shown to yield remarkable coding gains close to theoretical limits, yet admitting a relatively simple iterative decoding technique. Serially concatenated convolutional code (SCCC) proposed by S.Benedetto may...
Zero knowledge sets is a new cryptographic primary in- troduced by Micali, Rabin, and Kilian in FOCS 2003. It is intensively investigated recently. However all schemes follow the basic frame by Micali et al. That is, the schemes employ Merkle tree as basic frame and mercurial com- mitments as commitment units to nodes of the tree. The proof for any query constitutes of an authentication chain. We...
In this paper, we propose an internally adaptive LDPC coded ultra wideband-impulse radio (IALC-UWB-IR) system which is able to adaptively select the code rate of the LDPC code and the number of pulse repetitions. Performance of the proposed system is evaluated under the UWB multipart channel proposed in the IEEE 802.15.3a standard, and the selective-RAKE receiver with maximal radio combining is used...
With the rapid development of information technology and the gradual extension of information technology to enterprise, ERP systems become more and more complex and some new requirements that focus on both manufacturing activities and the supply chain are brought forward. To address these problems, a MAERP system architecture has been developed, in which the agents are classified into four types:...
To improve learning performance of boosting method, boosting learning procedure is divided into two sequential stages which are named reducing fitting error stage and reducing variance stage according to the idea of generalization error of boosting method composed of bias and variance which was originally proposed by Breiman. Traditional sampling methods such as roulette wheel selection is suitable...
