Learners enrolled: 4126 | Exam registration: 177

ABOUT THE COURSE:
This course will provide an advanced level understanding of a wireless communication system. Starting with the overview of wireless systems and standards, the students will study the fundamental capacity limits of wireless channels along with transmission strategies to maximize the theoretical capacity The course will also cover fundamental coding techniques such as block, convolutional and trellis coding for wireless channels and will also touch upon the recent developments in concatenated, turbo and LDPC codes. The students will also learn the benefits of applying adaptive modulation and coding strategies in wireless channels to enable robust and spectrally efficient communication. This course will also introduce students to MIMO communications and space time block codes which will be followed by multiuser systems and networks. Finally, the course will share insights and possible technologies for the next generation of wireless communication systems.

Instructor bio

Prof. Vivek Ashok Bohara

IIIT-Delhi

Prof.Vivek Ashok Bohara received the Ph.D. degree from Nanyang Technological University, Singapore, in 2011. From 2011 to 2013, he was a Postdoctoral Researcher (Marie Curie fellowship) in ESIEE Paris, University Paris-East where he was actively involved in designing and implementing critical blocks for wideband RF transmitters. Specifically, he proposed numerous green communication techniques to reduce power consumption and increase efficiency of nonlinear high power amplifiers used in RF transmitters. In 2013, he joined IIIT-Delhi, India, where he is currently Professor and Head, Department of Electronics and Communication Engineering. He has authored and coauthored over 100 publications in major IEEE/IET journals and refereed international conferences, two book chapters, and three patents. Dr. Bohara also supervises the Wirocomm Research Lab at IIIT Delhi which deals with state of the art research in wireless communication and allied area and is also the co-founding faculty member for Li-Fi Centre of excellence @ IIIT-Delhi which is supported by India-EU standardization project. His research interests are next-generation communication technologies such as Visible Light Communication (VLC), hybrid RF-VLC communication, integration of optical communication with intelligent reflective surfaces (IRS), UAV, and vehicular communication. prof.Bohara received First Prize in National Instruments ASEAN Virtual Instrumentation Applications Contest in 2007 and 2010. He was also the recipient of the Best Paper Award at the IEEE ANTS 2022 and the best poster and demo awards at IEEE Comsnets 2016 and 2023 conferences respectively.
