A joint scheme combining error-control coding (ECC) with complex-field coding (CFC) is proposed for space-time communications through flat or frequency-selective fading multiple-input multiple-output (MIMO) channels. It is shown that the diversity gain of this joint coding scheme is the product of the free distance of the ECC, the complexfield block encoder size, and the number of receive anten...

This paper simplifies an existing coding scheme for the two-receiver discrete memoryless broadcast channel with complementary receiver side information where there is a passive eavesdropper and individual secrecy is required. The existing coding scheme is simplified in two steps by replacing Wyner’s secrecy coding with Carleial-Hellman’s secrecy coding as well as removing additional randomness ...

This paper proposes C&M, a novel network coding scheme to deal with both inter-flow and intra-flow traffic in wireless networks. Prior work on wireless network coding design belongs to either inter-flow network coding or intra-flow network coding. C&M attempts to combine advantages of both network coding approaches to develop a more efficient network coding scheme. Based on COPE, C&M allows eac...

This paper presents a new fractal image coding (FIC) scheme to exploit the self-similarly at the same resolution scale in natural images. The new scheme can assure the convergence of FIC transforms without some limiting conditions like Zhao’s, and we also give the convergence proof of our new scheme in this paper. Our scheme also uses a recursive scheme feeding the coding results back to update...

Network coding refers to a scheme where a node is allowed to generate output data by mixing (i.e., computing certain functions of) its received data. The unique characteristics of wireless medium renders network coding particularly useful. For instance, network coding can be used to achieve the minimum energy-per-bit for multicasting in a wireless ad hoc network. In addition to optimizing energ...

We developed a Bayesian network coding scheme for annotating biomedical content in layperson-oriented clinical genetics documents. The coding scheme supports the representation of probabilistic and causal relationships among concepts in this domain, at a high enough level of abstraction to capture commonalities among genetic processes and their relationship to health. We are using the coding sc...

A new coding scheme is proposed for two-tone image contours. The basic idea is to detect digital line segments on the contour and code them using fixedor variable-length codewords; the present work deals mainly with fixed-length codewords. It is demonstrated that the conventional contour run length coding by Freeman's chain code is a special case of this scheme. The data compressibility of the ...
