Improved Nyquist pulse shaping filters for generalized frequency division multiplexing
Full text linkGeneralized Frequency-Division Multiplexing (GFDM) is one of the multicarrier modulation schemes currently under study for next generation 5G cellular networks. One of the main characteristics of GFDM is the low out of band emission that is achieved by means of a flexible time-domain pulse shaping of individual subcarriers. In the paper, we propose to use improved Nyquist pulse shaping filters which have been originally introduced in the context of single-carrier modulation schemes for reducing the sensitivity to symbol timing error due to their higher eye opening and smaller maximum distortion. Here we consider their use in GFDM and evaluate their symbol error rate (SER) performance in case of 16-QAM transmission over an additive white Gaussian noise channel. Moreover, we also considered the concept of the wavelet for better time-frequency localization of the pulse shaping filters by using the Meyer auxiliary function. Numerical results are reported to demonstrate the superior SER performance achieved by the proposed improved Nyquist pulse shaping filters in comparison to that achieved with conventional Nyquist pulse shaping filters
The effectiveness of influencer marketing on social media for home grown Indian brands
No full textIn India, the mobile phone revolution has changed several aspects of life, especially the business of advertising and marketing. Influencer marketing on social media using endorsements and product mentions from influencers that was earlier confined to celebrities and bloggers has grown bigger. Brands are re-imagining their businesses of marketing their products/services by building communities and roping in normal people as content creators. Instagram, YouTube and Facebook are becoming an instant hit allowing people to share reels, pictures/videos instantly. Influencers are people with a huge follower base on some or all of the social media platforms and brands are increasingly roping in these influencers to create a pull in the market for their products/services. These thought leaders create content to influence the idea of people online

Fostering Resilient Business Ecosystems and Economic Growth: Towards the Next Normal
No full textThis Conference Proceedings volume contains the written versions of most of the contributions presented during the Second International Conference on Fostering Resilient Business Ecosystems and Economic Growth: Towards the Next Normal. Like in the previous year, it took place online from April 27-29, 2022. The Conference provided a setting for discussing recent developments in various topics, including Marketing, OB & HRM, Entrepreneurship, Strategic Management, Operations Management, Economics, Public Policy, Business Analytics, International Business, Finance, and Accounting. The Conference has been a good opportunity for participants from 100s of Institutes from India and abroad. The inclusion of Keynote speeches in every track presentation has been highly appreciated, even for the speakers' efforts to present the ideas and methods in a lively and accessible way. We want to thank all participants for their contributions to the Conference program and their contributions to these Proceedings. Many thanks go to Soetomo University, Indonesia and AIMS, in collaboration with whom we have organized the International Conference for the second time in a row
On the Modeling of Inter-Sub-Symbol Interference in GFDM Transmission
Full text linkInter-sub-symbol interference (ISSI) refers to the interference that independently affects each group of sub-symbols transmitted on the same sub-carrier in generalized frequency division multiplexing (GFDM). In this letter, we derive a model to describe ISSI when transmission takes place over a frequency selective channel. The proposed model, which is derived by exploiting the discrete Gabor transform structure of GFDM, allows for the exact computation of the channel impulse response associated with each sub-carrier. Minimum mean-squared error and maximum likelihood receiver are considered as examples of the two different detection strategies based on the proposed modeling, together with the evaluation of their complexity. Simulation results demonstrate the improvement in the symbol error rate performance compared to another approach recently proposed in the literature that does not take into account the effect of ISSI

The future education delivery model
No full textThe online education system has got a major boost in recent years. Social distancing as a norm has created a big opportunity for the online education system. Content-wise the educational material may not change. But there is a drastic change in the “supply chain” and “logistics” of the delivery system of education. Hitherto students were going to the teachers to get educated. A 360-degree change has stepped into this basic model. The future education delivery model is one where the teachers will be reaching the students to deliver education. The new model has several advantages as well as limitations. This article takes stock of the future education delivery model in the form of an online education system. 100 students and 100 teachers were interviewed by way of a close-ended questionnaire to assess the feasibility of the model in terms of opportunities and challenges of the online model. The results are discussed in detail in the article. A wide agreement was found on the opportunities and challenges for online education as a future education delivery model. However, challenges were found to be overweighing the opportunities
A study of the adverse effects of shopping online
No full textDue to Corona pandemic all sectors of businesses shifted to online platforms, for their survival. Increased level of online shopping was seen due to imposed lockdowns and social distancing. Online shopping has number of advantages but there are certain disadvantages associated with the same and hence it’s important to be cognizant of such consequences. Cheating and frauds are the major concern of online buying and hence awareness should be created amongst the online shoppers. The study aims at exploring the disadvantages of online shopping. 120 respondents were surveyed from the city of Pune to collect their view about the disadvantages of online shopping
