Design Of Fountain Codes With Error Control
… via a comrelay by using distributed lt codes over a binary erasure channel (bec), and designing fountain codes with error control property by integrating lt codes with turbo codes over a binary input additive white gaussian noise (bi-awgn) channel. A simple yet efficient technique for …

LT Code Equations
The LT Code equations describe the process of encoding input symbols into an error correcting code that requires no feedback from the receiver. The mathematical process involved the development of LT Codes is important. This thesis address the issue of improving the understanding of the LT Code …

On The Design Of Physical Layer Rateless Codes
Codes that are capable of generating any number of encoded symbols from a given number of source symbols are called rateless codes. Luby transform (LT) codes are the first practical realization of rateless codes while Raptor codes are constructed by serially concatenating LT codes with high-rate …

Making Coding Practical: From Servers to Smartphones
… them is random network coding with random linear codes, in which a node in a network topology transmits a linear combination of incoming, or source, packets to its outgoing links. Theoretically, the high computational complexity of random linear codes (RLC) is well known, and is used to motivate …

Unequal Error Protection Raptor Codes
We design Unequal Error Protection (UEP) Raptor codes with the UEP property provided by the precode part of Raptor codes which is usually a Low Density Parity Check (LDPC) code. Existing UEP Raptor codes apply the UEP property on the Luby transform (LT) code part of Raptor codes. This approach …

Coding and scheduling in networks for erasures and broadcast
… perspective. A class of efficient and flexible codes known as fountain codes, is available to deal with erasures for the basic erasure channel. However, in the network applications that we consider, it remains a challenging problem to design efficient and scalable codes. For an erasure code, the …
