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

Low error floor LT coding algorithm by using fixed-length node classification window [PDF]
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 ...

Quasi-cyclic generalized ldpc codes with low error floors [PDF]
IEEE Transactions on Communications, 2007 In this paper, a novel methodology for designing structured generalized low-density parity-check (G-LDPC) codes is presented. The proposed design results in quasi-cyclic G-LDPC codes for which efficient encoding is feasible through shift-register-based circuits. The structure imposed on the bipartite graphs, together with the choice of simple component

Constellation labeling maps for low error floors [PDF]
IEEE Transactions on Wireless Communications, 2007 A constellation labeling map is the assignment of a bit pattern to each symbol in a signal-set constellation. In a system with iterative decoding and demodulation, the error floor of the bit error rate is highly dependent on the labeling map. A simple class of labeling maps that significantly lower the error floors is presented.

Effects of transport time and feeding type on weight loss, meat quality and behavior of broilers [PDF]
Animal Bioscience, 2022 Objective The purpose of this study is to determine the optimal time of transportation of floor-feed and scatter-feed broilers. Methods Eighty healthy Arbor Acres (AA) broilers (21-day-old, 624.4 g, male, standard error = 6.65) were selected and randomly
