Rateless Code Profiles Design for Uplink C-RAN under Block Fading Channel

International Conference on Wireless Communications and Signal Processing, 2018
This paper considers a single user uplink transmission system based on rateless code in Cloud Radio Access Network (C-RAN) under block fading channel. The system consists of a single user, a cluster of remote radio heads (RRHs), and a building baseband ...

Rateless Code-Aided Transmission Scheme to Achieve Secrecy in a Delay-Constraint Environment

International Workshop on Ant Colony Optimization and Swarm Intelligence, 2019
This paper analyses a secure transmission scheme using rateless codes (RC). As per the characteristic of the RC, receiver has to accumulate sufficient number of packets to reconstruct the entire source file. By utilizing the aforementioned characteristic,

Rateless space-time coding

Proceedings. International Symposium on Information Theory, 2005. ISIT 2005., 2005
Rateless codes are good codes of infinite length that have the property that prefixes of such codes are themselves good codes. This makes them attractive for applications in which the channel quality is uncertain, where systems transmit as much of a codeword as necessary for decoding to be possible.

Rateless-coded hybrid ARQ

2007 6th International Conference on Information, Communications & Signal Processing, 2007
Recently, hybrid-ARQ attracts significant research efforts due to the emergence of high speed data packet access (HSDPA) standard. Turbo-coded hybrid-ARQ was reported to have very good performance under block fading channels. In this paper, we investigate new hybrid ARQ schemes using rateless codes.

Rateless coding for wireless relay channels

Proceedings. International Symposium on Information Theory, 2005. ISIT 2005., 2005
We propose a novel coding framework for wireless relay channels based on rateless codes, which allows for a natural extension to multiple antenna and multiple relay settings. The relaying protocol is half-duplex, and relays independently choose when to collaborate, if at all.

Rateless Multilevel Coding and Applications

GLOBECOM 2009 - 2009 IEEE Global Telecommunications Conference, 2009
We propose a novel communication scheme that combines rateless transmission and multilevel coding (MLC). The scheme is able to attain a throughput that is equal to the constellation-constrained channel capacity. It is particularly useful in cases where the celebrated bit-interleaved coded modulation (BICM) would leave significant gaps to the channel ...
