This paper reports educational research in Electronics and Telecommunication Engineering, emphasizing the teaching and assessment of Digital Wireless Communication Systems. The study explores simulation-based learning through the design of a professional-grade framework modelled on Digital Mobile Radio (DMR). As part of a reformed engineering examination, 85 groups of second-year undergraduates (four students each) were assigned unique problem statements leading to the simulation of an end-to-end digital wireless communication system for voice and data using MATLAB Simulink. Real-time speech from speakers of varied gender, age (20–50 years), and linguistic backgrounds (Marathi, Hindi, English) served as input. Each group implemented different combinations of source coding, channel coding, and modulation to ensure project diversity. Separate voice and data links were created, and systems were evaluated using objective and subjective metrics such as Bit Error Rate (BER), Mean Opinion Score (MOS), data rate, delay, and throughput. Results showed that about 50% of students achieved approximately 80% marks and rest cross 60% marks, indicating substantial conceptual gain. The work demonstrates how project-based learning (PBL), aligned with Outcome-Based Education (OBE), can enhance understanding of complex communication architectures. The study advocates integrating simulation-driven, problem-oriented strategies as effective pedagogical tools for teaching digital wireless communication in engineering curriculum.

摘要

This paper reports educational research in Electronics and Telecommunication Engineering, emphasizing the teaching and assessment of Digital Wireless Communication Systems. The study explores simulation-based learning through the design of a professional-grade framework modelled on Digital Mobile Radio (DMR). As part of a reformed engineering examination, 85 groups of second-year undergraduates (four students each) were assigned unique problem statements leading to the simulation of an end-to-end digital wireless communication system for voice and data using MATLAB Simulink. Real-time speech from speakers of varied gender, age (20–50 years), and linguistic backgrounds (Marathi, Hindi, English) served as input. Each group implemented different combinations of source coding, channel coding, and modulation to ensure project diversity. Separate voice and data links were created, and systems were evaluated using objective and subjective metrics such as Bit Error Rate (BER), Mean Opinion Score (MOS), data rate, delay, and throughput. Results showed that about 50% of students achieved approximately 80% marks and rest cross 60% marks, indicating substantial conceptual gain. The work demonstrates how project-based learning (PBL), aligned with Outcome-Based Education (OBE), can enhance understanding of complex communication architectures. The study advocates integrating simulation-driven, problem-oriented strategies as effective pedagogical tools for teaching digital wireless communication in engineering curriculum.
