Industrial Internet of Things (IIoT) is one of the key features of Industry 4.0 that stands for a new approach to design industrial processes using the latest technological advances. However, before implementing new processes, it is necessary to understand the characteristics and limitations that arise due to technical complexity of the system. To solve this ...

© 2021 IEEE.Non-Orthogonal Multiple Access (NOMA) is a promising technology for future Wi-Fi, In uplink NOMA, stations with different channel conditions transmit simultaneously at the same frequency by splitting the signal by power level. Since Wi-Fi uses random access, the implementation of uplink NOMA in Wi-Fi faces many challenges. The paper presents a data transmission ...

We consider a new signal-code construction for a special class of multiple access system over vector-disjunctive channel when users transmit some vector of bits of finite length L. We propose a special encoding and decoding algorithms for such transmission scenario. Our suggested methods of encoding and decoding on one hand have acceptable complexity for a ...

We consider a fractional 0-1 programming problem arising in manufacturing. The problem consists in clustering of machines together with parts processed on these machines into manufacturing cells so that intra-cell processing of parts is maximized and inter-cell movement is minimized. This problem is called Cell Formation Problem (CFP) and it is an NP-hard optimization problem ...

Generalized error-locating codes are discussed. An algorithm for calculation of the upper bound of the probability of erroneous decoding for known code parameters and the input error probability is given. Based on this algorithm, an algorithm for selection of the code parameters for a specified design and input and output error probabilities is constructed. The ...

We study the following computational problem: for which values of k, the majority of n bits MAJn can be computed with a depth two formula whose each gate computes a majority function of at most k bits? The corresponding computational model is denoted by MAJk o MAJk. We observe that the minimum value of k ...

In what follows a coded DHA FH OFDMA employing robust reception and concatenated coding construction is considered. The problem of employing Generalized Minimum Distance decoder as an outer code decoder is considered. The effectiveness of the proposed decision is verified by means of simulation. In particular performance of the communication system under intensive mixed interference ...

In what follows a channel model that describes a class of communication systems employing a certain nonparametric receiver is considered. In particular a block coded transmission via the channel under consideration and soft-input mismatched decoding are considered. The paper deals with a problem of finding an upper bound on the probability of erroneous decoding. In ...

We study Boolean circuit complexity in an infinite basis consisting of all Boolean functions that equal 1 only on sets of pair-wise incomparable tuples. It is known that lower bounds on the complexity of linear function, majority function and almost all boolean functions of $n$ variables are of the order $\sqrt n.$ We show that ...

Future generation communication systems will have to endure interference induced by communication systems operating within the same frequency bands. Recently several coded DHA FH OFDMA systems employing rank-based detectors able to solve this problem were proposed. Unfortunately such detectors have relatively high complexity. In what follows a reduced-complexity detector using only column sorting for a ...

We consider an uncoordinated multiple-access system that employs a modulation technique, in which the probability of suppressing the signal sent by a certain user can be considered negligible, to transmit information via a wireless channel (e.g. time hopping (TH) with pulse position modulation (PPM)).This channel can be considered as an A channel (channel without intensity ...
