I have a GRE score of 317 + 4.5 (appeared in August 2011) and a TOEFL score of 107 (appeared in August 2011). I wanted to apply for MS/MS+PhD in US Universities. I have a B.Tech degree with CGPA of 9.12 in Electronics and Communication Engineering (from National Institute of Technology Rourkela, India). Also I have a research paper published in IEEE Xplore through a student conference. I want to get a fellowship for my duration of study in US or atleast some scholarship in case of only MS. What universities would be best suitable for me ?
I am interested in Signal Processing/VLSI implmentation and would prefer to do my further studies on these areas. Please do advise on the universities that I should apply and what steps do I need to follow.

Thank you.
