Regular Courses:

Monsoon Semester:

Digital Communication Systems (ECE 340)/ Wireless Communications Evolution from 3G to 5G (ECE 537)

Winter Semester:

Wireless system implementation  (ECE 539)

MooC / Online Courses:

Optical Wireless Communications:

Delivered 6 lectures (1 hour per lecture) for Massive Open Online Course (MOOC) on "Optical Wireless Communications: Fundamental & Potential Applications with a Vision for 5G and Beyond". TSDSI and ETSI (European Telecommunications Standards Institute) have anchored the activities under this project from India and the EU, respectively. As a part of this project, the IIITD-CoE has designed relevant courses on LiFi and facilitated capacity building by supporting research collaborations and the exchange of experts between India and the EU. The content of this MooC is free of cost and is publicly available.

NPTEL SWAYAM (Coordinated by IIT Madras):

An online course on "Fundamentals of wireless communications" in Hindi is developed by me with National program on technology enhanced learning (NPTEL). This course covered the basics of wireless communication, including channel modelling, signal propagation, the effect of fading, performance metrics evaluation such as bit error rate and outage probability, MIMO, programming tutorial on MATLAB, assignments, and Quizzes. This course will be offered from July 2023 onward. So far, the course has received 750+ enrollments.

Teaching philosophy:

I have always followed a principle that one particular teaching / learning technique or methodology may not be applied to whole class. The technique or methodology has to be adapted or modified depending on the course contents, level of the course, students’ background and even number of students in the class.

I have offered many courses in IIIT-Delhi with varying class sizes and students at different levels of competence. From a first-year core course of Basic electronics with class size of 150+ to a purely elective course on wireless and cellular systems. For instance, the wireless communication course that I offer involves a significant amount of mathematical interpretations and derivations. I always endeavor that the theoretical concepts are supplemented with simulation results. Most of the assignments (and even projects) are simulation based where the students simulate the theoretical concepts studied during the lectures. This helps the students to comprehend and validate the theoretical concepts studied during the lectures.  

Summary of feedback from the students produced below here verbatim (without any correction for typos etc.)

•  Vivek Sir has a very practical approach towards every topic that he explains in class. Sir covers all the types of numerical including the tricky ones. He takes pains to explain the topic in a simple way. Items such as small scale and large scale fading, flat fading and frequency selective fading concepts are very well covered in class.

• Use of software to analyze the behavior of wireless communication system. Professor designed the course in very efficient way. Course covered the Practical aspect of Current wireless system. Course covers the latest telecom standards and is very useful in developing the concepts. course covers vast topics which are useful in Industry work environment. Professor is very interactive and is always encouraging students to be interactive which helps us to ask us any doubts without any hesitation

• Explain everything in detail with examples, numerical problems makes concept more clear.

• Coming from systems background I was able to learn a lot and also relate this acquired knowledge with my hardware knowledge. I liked his teaching skills and he prepares well before class.

• One of the best courses of this semester.

•  Pretty good professor and really enjoyed the course.

• Course content is great, instructor is great. Teaches in a very easy way though he speaks so fast that you can miss something in an instance...: D The fact that he revises all the things taught in previous lecture before starting a lecture is fantastic.

• One of the best teachers that I have had the opportunity to learn from. Every day, I found myself excited to be able to go and attend his lectures. Dr. Bohara goes out of the way to help students understand any concept.

• The course was very well structured and content was excellent. The course will be very helpful for those who want to pursue research in wireless communication domain. I have gained a lot out of this course which I would use in my research. Course also improved practical knowledge of wireless communication due to inclusion of USRP and LabVIEW.

• Knowledge of the instructor is impeccable and he cleared every simple as well as complex doubt efficiently.

• This course is one of the best research oriented course in IIITD.
