Hey guys! I’m a EEE student and will be a finalist next year! I need to chose a project for my master thesis and I’m sort of unsure.

I’ve always loved wireless/RF communications, specially microwave systems, but I am unsure about what to do for my thesis. I shortlisted 3 main things:
-Anti Jamming communication system
-XPIC radio link
-Long range microwave link (~300Km)

I am really passionate about the technology and I have 18 months to do this. I am very committed to the thesis.

Also, after finishing my studies I would love to do research. So I will be applying to the States (MIT, Stanford...) or to Europe (ETH/Cambridge/Imperial College/EPFL). And I’ve heard that for PhD positions they try and look for innovative/challenging dissertations.

Thanks in advance guys!

Welcome to AAC.

Have you discussed this with your thesis advisor?
Have you checked with the schools of interest whether they accept graduate transfers with advanced standing?

RE:
-Anti Jamming communication system
--> How far I can see this functionality is inherrent to any LORA(tm) transmitter and works rather effectively. The basic assumptions - tranmsitting is going in very wide frequency range simultaneously; power is adaptively adjusting by sellf; bit by bit parity control is provided; in case of parity defect the new and new and new demand to sent ill-fated bit is flagged, until certificate it was received is flagged.
-XPIC radio link
--> First hear it, cant comment.
-Long range microwave link (~300Km)
--> That is difficult to obtain even the half of km at the case of several GHz or the power must be terrible - up to Petawaats in the impulse like military radars have to have. That is one of the main causes why 3x200W 3,5-5GHz 5G phone stations (still the region over 5 GHz-60 GHz is not well covered by commercially available tower hardware) need to be installed EVERY 200 meters a one. And even if You will use a superstrong but rare needles with haigh peak power and "normal" averag power, the Earth ball bending radius is never cancelled, thus the radio-horizon sight distance is calculated as L=3.57 sqrt(h). Thus the 350 km demands a sqrt(h)=100 or h=10 000 meters high antenna. I am motivating its nonsense.

PS - Dont blame me if Your tutor will blame the ides, still it is on the edge of "anti-science", but there are some strong indications showing the "H-plane antennas" are giving some unbelievable strange and good result.

300 km = 188 miles. At that distance, the curvature of the earth is a major problem, requiring significant height above the average terrain and very stable support structures. The technical issues regarding propagation sound like a fun thing to delve into, but the physical requirements will be very expensive.
