LT Codes
We introduce LT codes, the first rateless erasure codes that are very efficient as the data length grows.
متن کاملAnalysis of LT Codes with Unequal Recovery Time
In this paper we analyze a specific class of rateless codes, called LT codes with unequal recovery time. These codes provide the option of prioritizing different segments of the transmitted data over other. The result is that segments are decoded in stages during the rateless transmission, where higher prioritized segments are decoded at lower overhead. Our analysis focuses on quantifying the e...
متن کاملCapstone Project: LT Codes
Erasure codes are a type of encoding of data, generally for transmission over a lossy medium, that survive deletions (erasures) of parts of the message.1 They are especially useful for transmission of data across a medium or network that can drop packets of data, when it is impractical for the receiver to be in constant communication with the sender. Given a file with K blocks, the sender gener...
متن کاملMultiple Configurations LT Codes
This paper introduces a new scheme of LT codes, named multiple configurations. In multiple configurations LT codes (MC-LT codes), multiple sets of output symbols are simultaneously provided to receivers for recovering the source data. Each receiver, without the need to send information back to the sender, is capable of receiving the output symbols generated by some configuration chosen accordin...
متن کاملFalcon Codes: Fast, Authenticated LT Codes
In this paper, we introduce Falcon codes, a class of authenticated error correcting codes that are based on LT codes [23] and achieve the following properties, for the first time simultaneously: (1) with high probability, they can correct adversarial symbol corruptions in the encoding of a message, and (2) they allow for very efficient encoding and decoding times, even linear in the message len...
