Analog network coding (ANC) as a simple implementation of physical layer network coding based on orthogonal frequency division multiplexing (OFDM) has been proposed to increase the network capacity and reliability of bi-directional link between a pair of users. In ANC protocol, an information between a pair of users is exchanged through two orthogonal time phases (i.e., multiple-access and broadcast phases). On the other hand, the phase noise (PN) introduces phase offset and inter carrier interference (ICI) to the useful signal. Thus, in ANC scheme PN will affect the useful signal during both multiple-access and broadcast phases. In this article, we present a performance analysis of ANC scheme using OFDM in the presence of PN in frequency-selective fading channel. We derive the total composite variance of ANC scheme in the presence of PN to obtain the signal-to-interference-plus-noise ratio (SINR) expression. Then, we evaluate the system's performance in terms of bit error rate (BER), SINR degradation, and ergodic capacity through both numerical and computer simulations. Computer simulated average BER has been consistent with the numerical results, validating the presented analysis. Our results have shown that the ANC scheme is more sensitive to the PN introduced during the broadcast phase (i.e., at destination) than during the multiple-access phase (i.e., at relay). This is because of the higher ICI to the useful signal and enhanced noise due to the imperfect self-information removal at the destination. In addition, the performance degradation of ANC scheme based on OFDM in the presence of PN is highly expressed for the PN linewidth values up to 20 Hz.

The study presented in this paper explored the relationship between corporate entrepreneurship and business model innovation of companies in Bosnia and Herzegovina (B&H) after the COVID-19 pandemic. In particular, the authors aimed to analyze how the individual dimensions of corporate entrepreneurship influence business model innovation by using the dynamic capabilities view. The study empirically analysed a sample of 100 companies using regression analysis. The findings revealed that each dimension of corporate entrepreneurship positively and significantly impacts business model innovation. Innovativeness, proactiveness, risk-taking, autonomy, and competitive aggressiveness positively affected the innovation of the business model. The results of this study confirm that entrepreneurial initiative is a good predictor of a company’s ability to innovate business models. The implication for management is to deepen the understanding of how corporate entrepreneurship promotes and shapes an innovative business model. This increases companies’ success and overall well-being in B&H after the COVID-19 pandemic.

The Internet of Things (IoT) is one of the key technologies for the digital transformation of both business and society. The paper primarily aims to investigate the structure and dynamics of academic publications in English dealing with issues of IoT development – from a marketing perspective, using methods of systematic mapping, i.e., co-citation analysis, bibliographic coupling, and analysis of the co-occurrence of keywords in the Scopus and Web of Science (WoS) databases. Analysis of research papers enables the identification of the most influential articles, papers, and journals, as well as visualization of the keywords and co-authorship co-occurrences. There has been an exponential increase in studies on IoT applications in marketing, indexed in Scopus and WoS citation databases. An insight into analyzed papers shows that companies utilize large amounts of data generated by the IoT to gain insights into customers’ supply and value creation, which helps strengthen their relationships with customers and pursue more efficient marketing policies and practices, ultimately leading to a competitive advantage. The IoT is expected to evolve into a vast network that includes smart devices and significantly influences people’s behavior, especially decision-making at different stages of the purchasing process.

: The aim of this study is to examine the effect of plant fat sources in sheep feed on somatic cells and the total number of microorganisms in raw milk samples obtained from 210 sheep, breed Pramenka in Una-Sana Canton. The research was conducted in three periods: winter, spring and summer. The herd was divided into experimental and control groups of sheep. In the experimental groups of sheep in each period of the study, omega-3 supplements were added to the diet, namely extruded flaxseed in the amount of 3.5%. The influence of added omega-3 supplements on the microbiological parameters of raw sheep milk, which was milked from experimental and control groups of sheep every fifteen days of the experiment in all periods of the study, was examined. Analysis of variance (ANOVA) found that during the winter and summer feeding period there is a statistically very significant influence of both experimental factors (treatment and period) on the total number of microorganisms and somatic cells in raw sheep milk (p <0.001). In the spring diet in somatic cells, factor treatment did not show a statistically significant effect (ns).
