Rateless Unsourced Random Access
IEEE Wireless Communications and Networking Conference, 2022Massive Machine-Type Communication (mMTC) is expected to support massive connectivity for a large number of machine-type devices (MTDs). In many practical applications, the base station (BS) only needs to recover the list of received messages instead of ...

Rateless Sum-Recovery Codes For Distributed Non-Linear Computations
Information Theory Workshop, 2022We address the problem of slowdown caused by straggling nodes in distributed non-linear computations. Many common non-linear computations can be written as a sum of inexpensive non-linear functions (e.g. Taylor series).

Rateless codes on noisy channels
International Symposium onInformation Theory, 2004. ISIT 2004. Proceedings., 2004This paper studies the performance of two classes of rateless codes (LTand Raptor codes) on noisy channels such as the BSC and the AWGNC. We find that Raptor codes outperform LT codes, and have good performance on a wide variety of noisy channels.

Rateless Codes Based on Punctured Polar Codes
2018 15th International Symposium on Wireless Communication Systems (ISWCS), 2018Polar codes are the first binary linear block codes provably achieving the symmetric capacity of arbitrary binary-input discrete memoryless channels. However, in their original design, their block length is limited to integer powers of two, a constraint that may be relaxed by puncturing.

Rateless coding over fading channels
IEEE Communications Letters, 2006We propose a framework for communication over fading channels utilizing rateless codes. An implementation using fountain codes is simulated, demonstrating that such a scheme has advantages in efficiency, reliability and robustness over conventional fixed-rate codes, particularly when channel state information is not available at the transmitter.

Efficient Reliable Wireless Communications through Raptor Codes and Rateless Codes with Feedback
ICC 2022 - IEEE International Conference on Communications, 2022Multi-connectivity can increase the reliability of wireless communications by orders of magnitude due to an increased diversity. However, simply copying packets and sending them on multiple links in parallel, i. e., as standardized as packet duplication,

Error Correction for Rateless Codes
2009 IEEE 13th Digital Signal Processing Workshop and 5th IEEE Signal Processing Education Workshop, 2009Rateless codes for erasure channels were recently proposed by Luby with very efficient coding and decoding schemes. However, designing an efficient decoding rateless code for Binary Error Channel (BEC), still remains a difficult problem. In this work we propose a rateless decoding algorithm for the BEC using a coding matrix G with a high level of ...

Low-Latency Distributed Inference at the Network Edge Using Rateless Codes (Invited Paper)
International Symposium on Wireless Communication Systems, 2021We propose a coding scheme for low-latency distributed inference at the network edge that combines a rateless code with an irregular-repetition code. The rateless code provides robustness against straggling servers and serves the purpose of reducing the ...

Rateless Coding and Relay Networks
IEEE Signal Processing Magazine, 2007A framework for coding over relay channels using rateless codes is the intersection of two active areas of research in communications; namely relay networks and rateless coding. We demonstrate that there is a very natural and useful fit between these two areas and describe some design challenges and implementation considerations for this framework. The

Rateless Joint Source-Channel Coding, and a Blueprint for 6G Semantic Communications System Design
arXiv.orgThis paper introduces rateless joint source-channel coding (rateless JSCC). The code is rateless in that it is designed and optimized for a continuum of coding rates such that it achieves a desired distortion for any rate in that continuum.
