Enhancing short-packet communications: BLER performance in RIS-assisted ambient backscatter NOMA systems. [PDF]
Short-packet communication (SPC) is a key enabler for ultra-reliable low-latency communication (URLLC) in next-generation wireless networks. In this paper, we investigate the block error rate (BLER) performance of a reconfigurable intelligent surface ...

An analytical approximation to the block error rate in Nakagami-m non-selective block fading channels [PDF]
With few exceptions, an analytical closed-form expression for the block error rate (BLER) is lacking in block fading channels. Thus, the BLER is often obtained by numerical methods, such as Monte-Carlo simulations, resulting in additional computational ...

Improved PEG-Based Construction of Analog Fountain Codes [PDF]
This paper proposes an improved progressive edge-growth (PEG) construction of analog fountain codes (AFCs). During edge selection, it simultaneously allocates weight coefficients in descending order.

On the Performance Evaluations of Cooperative Retransmission Scheme for Cell-Edge Users of URLLC in Multi-Carrier Downlink NOMA Systems [PDF]
Non-orthogonal multiple access (NOMA) has a key feature that the cell-center user (CCU) has prior information about the messages of the cell-edge user (CEU) in the same user-pair.

An Enhanced Belief Propagation Flipping Decoder for Polar Codes with Stepping Strategy [PDF]
The Belief Propagation (BP) algorithm has the advantages of high-speed decoding and low latency. To improve the block error rate (BLER) performance of the BP-based algorithm, the BP flipping algorithm was proposed.

Quasi-Optimal Path Convergence-Aided Automorphism Ensemble Decoding of Reed–Muller Codes [PDF]
By exploiting the rich automorphisms of Reed–Muller (RM) codes, the recently developed automorphism ensemble (AE) successive cancellation (SC) decoder achieves a near-maximum-likelihood (ML) performance for short block lengths.

SCF Decoding Algorithm Based on Log Likelihood Ratio and Channel Polarization Reliability [PDF]
The traditional Successive Cancellation bit-Flipping(SCF) decoding algorithm only uses the absolute value of Log Like Ratio(LLR) to measure the reliability of information bit decoding results, which leads to a high Block Error Rate(BLER) and more ...

PHY Abstraction Methods for OFDM and NOFDM Systems
In the paper various PHY abstraction methods for both orthogonal and non-orthogonal systems are presented, which allow to predict the coded block error rate (BLER) across the subcarriers transmitting this FEC-coded block for any given channel ...
