At 2:00 PM on September 26, 2023, the Intelligent Network and Computing Laboratory of the School of Computer Science is honored to invite Professor Lin Hai from Osaka Public University to give a lecture to the teachers and students of the laboratory in the Cross-Building 2 of Jiangwan Campus of Fudan University, presided over by Professor Gao Yue, Director of the Intelligent Network and Computing Center.
In the lecture, Professor Lin Hai first reviewed the LTV channel model and discussed the pulse response in DD domain. He then reintroduced the basics of multi-carrier (MC) modulation, including transmission strategies, pulse design principles, and implementation methods. Then, Professor Lin Hai proposed a transmission strategy based on pulse function, and designed the corresponding delayed Doppler multi-carrier (DDMC) modulation scheme. Most notably, he introduced the concept of delayed Doppler domain orthogonal pulses (DDOP) and proposed ODDM modulation techniques based on DDOP. Through the fuzzy function analysis of DDOP, Professor Lin Hai showed the perfect orthogonal property of DDOP relative to DD resolution, thus proving the applicability of ODDM/DDMC waveforms in ISAC systems.
Professor Lin Hai's presentation was deep and simple, bringing participants a comprehensive understanding of orthogonal delay Doppler division multiplexing. His presentation and explanation led to a deeper understanding of the potential of the technology and expectations for its future applications in the field of wireless communication and perception. In addition, Professor Lin Hai's personal experience and rich experience in related fields also brought inspiration and reference to the participants.
This lecture not only provided an opportunity for participants to learn and communicate, but also showed the importance and application prospect of orthogonal delay Doppler division multiplexing technology in future communication systems. The students in the laboratory are looking forward to continuing to study and explore the development of this field in the future.
