Error Floor Analysis of Coded Slotted ALOHA over Packet Erasure Channels [PDF]
, 2014 We present a framework for the analysis of the error floor of coded slotted ALOHA (CSA) for finite frame lengths over the packet erasure channel. The error floor is caused by stopping sets in the corresponding bipartite graph, whose enumeration is, in ...

Coding and Detection Schemes for Ambient Backscatter Communication Systems
IEEE Access, 2017 Ambient backscatter technology has attracted much attention recently, because it enables battery-free devices, such as tags or sensors, to communicate through wireless energy harvesting and radio backscattering. Existing studies about ambient backscatter

Error Floor Analysis of Irregular Repetition ALOHA
ICC 2022 - IEEE International Conference on Communications, 2022 With the rapid expansion of the Internet of Things, the efficient sharing of the wireless medium by a large amount of simple transmitters is becoming essential. Scheduling-based solutions are inefficient for this setting, where small data units are broadcast sporadically by terminals that most of the time are idle. Modern random access has embraced the

IEEE Access, 2018 In this paper, we study the performance of spatial modulation (SM) employing Euclidean distance-based antenna selection (EDAS) operating in a realistic error-infested feedback channel, which has hitherto only been studied under ideal feedback channel ...

UP-GDBF: A 19.3 Gbps Error Floor Free 4KB LDPC Decoder for NAND Flash Applications
IEEE Open Journal of Circuits and Systems, 2022 An error floor phenomenon, decoding performance, and throughput are three major concerns for LDPC decoders in NAND Flash applications. With a penalty method and an active iteration mechanism, we present a Unified Penalty Gradient Descent Bit Flipping (UP-

Low error floor LT coding algorithm by using fixed-length node classification window
Tongxin xuebao, 2021 To solve the problem of high error floor for LT codes in additive white Gaussian noise (AWGN) channels, an improved coding scheme was designed.A fixed-length classification window was used to sort out the information nodes with relatively small degrees ...

Evolutionary Algorithm Aided Interleaver Design for Serially Concatenated Codes [PDF]
, 2011 In this paper, we propose an algorithm for designing the interleavers of Serially Concatenated Codes (SCCs), in order to increase the Minimum Hamming Distance (MHD) between the legitimate permutations of the encoded bit sequence and hence to improve the ...

Beating Stellar Systematic Error Floors Using Transit-based Densities
The Astronomical Journal, 2023 Abstract It has long been understood that the light curve of a transiting planet constrains the density of its host star. That fact is routinely used to improve measurements of the stellar surface gravity and has been argued to be an independent check on the stellar mass. Here we show how the stellar density can also dramatically improve
