Augmented LT codes over binary extension fields with increased ratio of full‐degree columns
Electronics Letters, Volume 60, Issue 5, March 2024.An augmented scheme of LT codes is proposed to improve the decoding success rate. The method involves substituting the 1 in full‐degree columns of the generator matrix of conventional LT codes with binary extension field elements and simultaneously increasing the ratio of full‐degree columns in the ideal soliton distribution, which allows for higher ...

Whether and Where to Code in the Wireless Relay Channel
, 2012 The throughput benefits of random linear network codes have been studied extensively for wirelined and wireless erasure networks. It is often assumed that all nodes within a network perform coding operations.

Throughput of Rateless Codes Over Broadcast Erasure Channels [PDF]
IEEE/ACM Transactions on Networking, 2012 In this paper, we characterize the throughput of a broadcast network with n receivers using rateless codes with block size K. We assume that the underlying channel is a Markov modulated erasure channel that is i.i.d. across users, but can be correlated in time. We characterize the system throughput asymptotically in n.

HARQ‐Chaotic: Analog Chaotic Code Applied in HARQ Scheme of Wireless Communication System
Wireless Communications and Mobile Computing, Volume 2019, Issue 1, 2019., 2019 This paper proposes a novel symbol‐level combining hybrid automatic repeat request (HARQ) scheme based on analog chaotic code and named HARQ‐Chaotic. The transmitter of HARQ‐Chaotic adopts analog chaotic code to encode Quadrature Amplitude Modulation (QAM) symbols of retransmission packets to combat fading and noise. As the analog chaotic code can only

Timely Updates over an Erasure Channel [PDF]
, 2017 Using an age of information (AoI) metric, we examine the transmission of coded updates through a binary erasure channel to a monitor/receiver. We start by deriving the average status update age of an infinite incremental redundancy (IIR) system in which ...

Efficient Symbol Sorting for High Intermediate Recovery Rate of LT Codes
, 2010 LT codes are modern and efficient rateless forward error correction (FEC) codes with close to channel capacity performance. Nevertheless, in intermediate range where the number of received encoded symbols is less than the number of source symbols, LT ...
