Biography
Dr. Sajjad Ali is an Associate Professor in the Department of Telecommunication Engineering at Mehran University of Engineering and Technology (MUET), Jamshoro. He has served in the department as Lecturer, Assistant Professor, and Associate Professor, and has been involved in teaching a range of telecommunication subjects including Transmission & Switching Systems, Broadband Digital Networks, Mobile Network Planning, Optoelectronics, Voice and Data Networking in CDMA2000, Principles of Telecommunication Traffic Engineering, Wireless Communications, and Digital Communication.
His research interests are primarily in wireless communications, particularly cellular communication systems. His earlier research work focused on Peak-to-Average Power Ratio (PAPR) reduction in MC-CDMA and pilot contamination problems in massive MIMO communication systems. His current research interests include machine learning applications in communications and information technology.
Before joining MUET, he worked as an Operation & Maintenance Engineer with Telenor Pakistan in the Department of BSS, Hyderabad, where his responsibilities included preventive maintenance of Base Transceiver Stations (BTS) in the region and media expansions.
His academic background includes a PhD in Communication and Information Systems from Dalian University of Technology, China, an M.E. in Communication Systems and Networks from MUET, and a B.E. in Telecommunication Engineering from MUET. His doctoral dissertation focused on pilot contamination elimination and PAPR reduction in wireless communication systems.
