正交時頻空間(orthogonal time frequency space; OTFS) 系統 L1

講師：Prof. Saif Khan Mohammed (印度理工學院德里分校電機工程系) ◆ 說明：本微課程，從基本原理出發，介紹「正交時頻空間(OTFS)調變」技術。這項技術被視為下世代（包含6G）通訊系統中非常先進且持續發展的研究領域。課程第一單元將討論OTFS的物理和理論基本原理。其次，課程第二單元會針對MC-OTFS架構，介紹如何設計發射機、接收機、通道估計演算法及性能評估指標。最後，在課程第三單元中會介紹多使用者、雷達偵測等應用，以及基於深度學習的收、發機設計。讓更多人了解OTFS對下世代通訊系統的突破性貢獻。 ◆ Abstract: 6G and next generation communication systems introduce new use cases which involve high delay and Doppler spread channel scenarios for which traditional time and frequency domain signal processing cannot achieve the desired performance targets. Performance in such linear time-varying (LTV) channels can be achieved through signaling and information processing in the delay-Doppler domain. 6G systems (as envisaged by IMT2030) are expected to address three new types of use cases, (i) ubiquitous communication, (ii) integrated sensing and communication, and (iii) AI for wireless communication. This course teaches Zak-theory based mathematical framework which forms the basis for DD domain signal processing. The course also applies this framework to derive, (i) Zak-OTFS modulation for reliable communication in doubly-spread LTV channels which enables ubiquitous communication in 6G systems, (ii) Zak-OTFS based integrated sensing and communication and Radar, and (iii) Zak-OTFS as an enabler for AI in wireless communication.
