Research topics for Wireless Communication and DSP
Hi guys, right now i'm about to finish my 2nd year in ECE at a college in Asia. I have been really enjoying the maths and courses like Digital Comm, Signals classes and a Network class. In my free time i also have been learning some hardware skills like using STM32 or FPGA though i do not enjoy as much as doing simulations.
I'm planning on taking a Master in another country and do some research in the field of Wireless communication. So, I have some questions.
Is the physical layer development research still relevant? Should I look out more for opportunity in layer 2 or 3 or higher? I have the impression that the physical layer research has been really repetitive and no new innovations.
What are some career options or jobs titles that I should look for? For example like embedded, DSP, network protocol engineer,...etc.
Is this field good to migrate to another country and what are some promising research in this area? (like maybe ISAC, QKD,...etc)
Thanks a lot for reading!
