The character of Parallel Concatenated LDPC codes with rate-compatible is analyzed. An Incremental redundancy hybrid ARQ scheme based on parallel concatenated LDPC codes is introduced. We studied the throughput of the new HARQ scheme and obtained the closed_form solutions. Furthermore, the throughput of the new HARQ scheme is simulated. It shows that for arbitrary block fading channel, comprisi...

Hybrid networks consisting of satellite links and mobile ad hoc networks present a series of challenges due to different packet-loss patterns, delay, and, usually, scarce available bandwidth. In this scenario, redundant encoding, in the form of Forward Erasure Correction (FZC) codes [1],[2], can provide an effective protection against losses in multicast videoconferencing and video streaming ap...

Partial MDS (PMDS) and sector-disk (SD) codes are classes of erasure correcting that combine locality with strong correction capabilities. We construct PMDS SD local regeneration where each code is a bandwidth-optimal regenerating code. In the event node failure, these reduce both, number servers have to be contacted as well amount network traffic required for repair process. The constructions ...

In this paper we propose a hybrid maximum likelihood decoding (MLD) for linear block codes. For the reliable data transmission over noisy channels, convolutional and block codes are widely used in most digital communication systems. Much more efficient algorithms have been found for using channel measurement information in the decoding of convolutional codes than in the decoding of block codes....

Strong rate-compatible codes is important to achieve high throughput in hybrid automatic repeat request with forward error correction (ARQ/FEC) systems in packet data transmission. This paper focuses on the construction of efficient rate-compatible low density parity check (RC-LDPC) codes over a wide rate range. The conventional approach of puncturing is first studied. Analysis on the code ense...

In this paper, we propose a new approach to construct a class of check-hybrid generalized low-density parity-check (CHGLDPC) codes which are free of small trapping sets. The approach is based on converting some selected check nodes involving a trapping set into super checks corresponding to a 2-error correcting component code. Specifically, we follow two main purposes to construct the check-hyb...

Given the expressive power of hybrid games, our goal is to explore how easy it is to model realistic games and what insights can be gained from these models. We explore three children’s games (Red Rover, Leap Frog and Red Light, Green Light) to provide examples of interesting multi-player, sometimes collaborative games. Throughout the modeling process we show what is easy to model and what is d...

In this paper “Digital Transceiver using Hybrid Ternary Technique” gives the details about digital transmitter and receiver with the design of a hybrid ternary line coding. Current applications of line codes are enormous in data transmission networks and in recording and storage of information systems. The applications include local and wide area networks both wireless and wire connected and th...

This paper outlines a straightforward, fast, and low-cost method to fabricate polydimethylsiloxane (PDMS) chips. Termed sandwich bonding (SWB), this method requires only a laboratory oven. Initially, SWB relies on the reversible bonding of a coverslip over PDMS channels. The coverslip is smaller than the substrate, leaving a border around the substrate exposed. Subsequently, a liquid composed o...

With increase in scale, the number of node failures in a data center increases sharply. To ensure availability of data, failure-tolerance schemes such as ReedSolomon (RS) or more generally, Maximum Distance Separable (MDS) erasure codes are used. However, while MDS codes offer minimum storage overhead for a given amount of failure tolerance, they do not meet other practical needs of today’s dat...
