Fountain Codes: LT And Raptor Codes Implementation
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 1
Abstract
Digital fountain codes are a new class of random error correcting codes designed for efficient and reliable data delivery over erasure channels such as internet. These codes were developed to provide robustness against erasures in a way that resembles a fountain of water. A digital fountain is rateless in a way that sender can send limitless number of encoded packets. The receiver doesn’t care which packets are received or lost as long as the receiver gets enough packets to recover original data. In this paper, the design of the fountain codes is explored with its implementation of the encoding and decoding algorithm so that the performance in terms of encoding/decoding symbols, reception overhead, data length, and failure probability is studied.

Hedge Algebras Tuning of PID Controller
In this paper, the author proposes a method modified on-line the parameters of the PID controller based on combining the hedge algebras control and model reference system. This proposal has inherited the adaption of hedg...
Direct Power Control of Three Phase PWM Rectifier based DSOGI-VF Estimator for No-Ideal LineVoltages Conditions
In this paper, direct power control (DPC) of three-phase pulse width-modulated rectifiers without line voltage sensors is presented. The new system is based on virtual flux (VF) using dual Second Order Generalized Integr...
A Case Elaboration Methodology for a Semantic Web Service Discovery System Based on CBR
The Case Based Reasoning is a paradigm of intelligent reasoning which consists on reusing results of previously solved problems (Source Cases) to solve new problems (Target Cases). It has been formalized as a five-step p...
M-EPAR to Improve the Quality of the MANETs
In MANET, power aware is important challenge issue to improve the communication energy efficiency at individual nodes. We propose modified efficient power aware routing (M-EPAR), a new power aware routing protocol that i...
Topic Trees And Chatbot Conversational Context
This article discusses the relation between topic-specific word trees (“ontologies”) and the retrieval of information from a chatbot‟s recent conversation – the conversational context. I assume the conversational context...
