Require Help for Final Year Project Selection

Hi I am a student of BSc Telecom Engineering. I believe that this site can be quite helpful in selecting my final year project.
I am interested in projects related with Antenna and DSP(but you can give your own suggestion),can be easily implemented on bachelor level and commercial(or cmrcializeable??).
If your suggested project is already implemented by you(or any close friend) please mention it in your post.
I will be very thankful if you give me a short tutorial of the project
(in the form of useful link/online chat). I am waiting for your quick reply.
