Skills and Expertise

Telecommunication engineering

I am totally familiar with software defined radio, cognitive radio, spread spectrum, information theory, coding, modulation schemes, transceiver structures, antenna, electromagnetic, ... . In addition, because of my job experience in Huawei and Nokia companies I had the chance to combine all theoretical information that I gained in university with real and practical scenarios as a LTE network planning and optimization engineer.

LTE/LTE-A technology

I have very deep insight about 4G technology as I worked 3 years in university to implement whole physical layer of the LTE and LTE-A in C++. After graduation I pursued my work on LTE in Huawei and then Nokia as LTE network optimizer engineer and it helped me achieve a very broad knowledge in the field of LTE/LTE-A.

C++ programming

I spent last 4 years on C++ programming and obtained solid background in object oriented programming and multi-threaded programming. I have  4 years experience of using gnuradio/C++ for implementation software defined radio. For example I have  written 8000 lines of C++ code to implement LTE eNodeB on USRP (www.ettus.com) as my Master's degree thesis and also I wrote 4000 lines of C++ code for implementing a fast frequency hopping spread spectrum modem on USRP.

Matlab and simulink

I have 7 years of experience in Matlab programming. I usually use Matlab for prototyping signal processing modules.

For example one of my Matlab scripts that I had developed when I was in bachelors degree for designing microwave transmission line using smith chart is uploaded in Mathwork website.

Ability to work in hard situations in a dynamic and multi-nationalty environment

I spent last 3 years in telecommunication industry in Huawei and Nokia companies as 3G/LTE RF engineer on live network and worked with so many Chinese, Indian, Pakstanian, Turkish, Egyptian and European people. During this period I learnt gradually how to work under pressure and accept other cultures and effectively communicate with them.
