# Bharath B. N

I received my doctoral degree from the Dept. of Electrical Communication Engineering, Indian Institute of Science, Bangalore on June 2013. My PhD advisor was Prof. Chandra R. Murthy. I worked in the area of reciprocal MIMO channel estimation. Currently, I am employed at Qualcomm Inc. as a senior engineer. My research interests include Information theory, Estimation theory, Machine learning, High dimensional statistics and Signal Processing applications in communication problems.

## Teaching experience

**I was a TA for the following courses:**

1. Detection and estimation theory (Spring 2010)

2. Matrix theory (Fall 2010)

3. Detection and estimation theory (Spring 2011)

**I was a TA for the following course:
Matrix theory (Fall 2012).**

*Course instructor: Prof. Chandra R. Murthy*

I found (among other standard “reference” books) the text book titled “Linear Algebra A geometric Approach” (an undergraduate level text) by S. Kumeresan very interesting. Also, I found a very good introduction to linear algebra in a book by Vinberg, titled “A course in Algebra” published by AMS publications. Although the main focus of the book is on abstract algebra, there is a substantial amount of linear algebra and geometry as well. Further, the development of the topic on the Jordon form seems to be very interesting. Subsequently, I will try to post some interesting problems and concepts in linear algebra and Matrix theory as a pdf attachment.

I have uploaded the course notes (rough sketch). Please let me know if there are any errors/typos (technical/non-technical) in the document.
