Throughput of Rateless Codes Over Broadcast Erasure Channels [PDF]

open access: yesIEEE/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

open access: yesWireless 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

Spinal codes [PDF]

open access: yes, 2012
Spinal codes are a new class of rateless codes that enable wireless networks to cope with time-varying channel conditions in a natural way, without requiring any explicit bit rate selection.

Rateless Protograph LDPC Codes for Quantum Key Distribution

open access: yesIEEE Transactions on Quantum Engineering
Information reconciliation (IR) is a key step in quantum key distribution (QKD). In recent years, blind reconciliation based on low-density parity-check (LDPC) codes has replaced Cascade as a standard de facto since it guarantees efficient IR without a ...

Adaptive demodulation using rateless erasure codes [PDF]

open access: yesIEEE Transactions on Communications, 2006
We introduce a rate-adaptive system in which the receiver demodulates only those bits that have a high probability of being correct, treating nondemodulated bits as erasures. Several sets of decision regions, derived using composite hypothesis testing, are proposed for 16-QAM and 16-phase-shift keying, which allow for the simple implementation of this ...

Iterative Relay Scheduling With Hybrid ARQ Under Multiple User Equipment (Type II) Relay Environments

open access: yesIEEE Access, 2018
In this paper, we propose an iterative relay scheduling with hybrid ARQ (IRS-HARQ) scheme, which realizes fast jump-in/successive relaying and subframe-based decoding under the multiple user equipment (UE) relay environments applicable to the next ...
