Statistical Degree Distribution Design for Using Fountain Codes to Control the Peak-To-Average Power Ratio in an OFDM System [PDF]
Entropy, 2022 Utilizing fountain codes to control the peak-to-average power ratio (PAPR) is a classic scheme in Orthogonal Frequency Division Multiplexing (OFDM) wireless communication systems.

An Opportunistic Error Correction Layer for OFDM Systems [PDF]
EURASIP Journal on Wireless Communications and Networking, 2009 We propose a novel cross layer scheme to reduce the power consumption of ADCs in OFDM systems. The ADCs in a receiver can consume up to 50% of the total baseband energy. Our scheme is based on resolution-adaptive ADCs and Fountain codes.

Multiple Access Analog Fountain Codes [PDF]
2014 IEEE International Symposium on Information Theory, 2014 In this paper, we propose a novel rateless multiple access scheme based on the recently proposed capacity-approaching analog fountain code (AFC). We show that the multiple access process will create an equivalent analog fountain code, referred to as the ...

Zigzag Decodable Fountain Codes [PDF]
IEICE ESS Fundamentals Review, 2016 This paper proposes a fountain coding system which has lower space decoding complexity and lower decoding erasure rate than the Raptor coding systems. The main idea of the proposed fountain code is employing shift and exclusive OR to generate the output ...

Secure Repairable Fountain Codes [PDF]
IEEE Communications Letters, 2016 In this letter, we provide the construction of repairable fountain codes (RFCs) for distributed storage systems that are information-theoretically secure against an eavesdropper that has access to the data stored in a subset of the storage nodes and the ...

Fountain Codes with Multiplicatively Repeated Non-Binary LDPC Codes [PDF]
2010 6th International Symposium on Turbo Codes & Iterative Information Processing, 2010 We study fountain codes transmitted over the binary-input symmetric-output channel. For channels with small capacity, receivers needs to collects many channel outputs to recover information bits.

Caching at the Edge with Fountain Codes [PDF]
2018 9th Advanced Satellite Multimedia Systems Conference and the 15th Signal Processing for Space Communications Workshop (ASMS/SPSC), 2018 We address the use of linear randon fountain codes caching schemes in a heterogeneous satellite network. We consider a system composed of multiple hubs and a geostationary Earth orbit satellite.

Expanding window fountain codes for unequal error protection [PDF]
2007 Conference Record of the Forty-First Asilomar Conference on Signals, Systems and Computers, 2009 A novel approach to provide unequal error protection (UEP) using rateless codes over erasure channels, named Expanding Window Fountain (EWF) codes, is developed and discussed.
