Basic Research Methodology in Wireless Communications: The First Course for Research-Based Graduate Students

Abstract

In this paper, we present an introductory course design for fresh research-based graduate students in wireless communications, which is planned to be delivered immediately after enrollment. The course aims at covering necessary research methodologies and the rudiments of wireless communications. Different from most graduate study curricula based on experiments, we design the course structure in an introductory manner by tailoring the course contents to a simplistic form and involving only simulations. We start by introducing the pedagogical background and our motivations for designing this course. Then, we present the fundamentals and the technological contents, followed by detailing the basic research methodology, strategies, and skills for deriving insightful analytical expressions and carrying out numerical simulations. We also verify the effectiveness of the course structure design by carrying out a teaching experiment and analyzing objective and subjective data collected from the experiment. By participating in this course, research-based graduate students are expected to gain a preliminary knowledge of the research methodology and strategies in the field of wireless communications as well as a research roadmap.

Enhanced Huffman Coded OFDM with \\Index Modulation

“…Finally, according to (6), (14) and the Huffman encoding rules, it is evident that there exist M K legitimate OFDM blocks adopting the same SAP. Hence, it is straightforward to explicitly express the average BLER as…”

“…Moreover, the rule must also lead to consistent evaluations for all scenarios. Therefore, to avoid unnecessary discussion regarding how to count bit errors when transmitted and erroneously decoded bit streams have different lengths, we adopt BLER as the error performance evaluation metric in this paper 6. A perfect Huffman tree is defined as the tree, on which all interior nodes have two children and all resultant leaves are with the same depth[49].…”

Prospect Theory for Human-Centric Communications

“…The information theory constructed by Claude E. Shannon in 'A Mathematical Theory of Communication' has been widely acknowledged as a landmark in telecommunications and the mathematical foundation of modern communication systems [41]. Developed from the information theoretic model, most communication system models consist of transmitter, channel, and receiver, in which objective noise, interference, impairments, and imperfection are taken into consideration [42]. For developing human-centric communications, communication system models should incorporate the fundamental mechanism of human perception after the receiving module.…”

PHY Research Is Sick but Curable: An Empirical Analysis

“…On the other hand, it is emphasized in [2] that the PHY academic research is of high importance, because we need to understand and model the behavior of high-frequency radio signal as well as to manage cross-cell interference when densifying communication networks in space and frequency spectrum. Also, the crucial role of the PHY research in engineering education and socio-technical milieu of wireless technology cannot be overlooked [9]. Although insightful and thought-provoking, the analyses and discussions of the pros and cons regarding the PHY academic research in all aforementioned articles are mainly given in a subjective manner, lacking rigorous analysis and quantitative evidence.…”
