There should have been questions like: explain to me LTE, WCDMA, GSM, CS and PS, etc.
I was literally not asked a question at all. He told me based off of my resume that I would be able to handle the workload.
Question from resume, school projects?
What is OFDM?
If signal is need to be transmitter from point A to B. Distance between point A and B is 200 miles. Will it be possible to send signal from point A to B without modulating signal from A to B? YES/ NO? and Why ?
What is fading? type?
OFDM = orthogonal frequency division multiplexing.
technique, method or scheme for digital multi-carrier modulation using many closely spaced subcarriers - a previously modulated signal modulated into another signal of higher frequency and bandwidth. Less
MIMO requires the RX/TX antennas to have low correlation, hence will work better if multi-path is present! So line of sight environment wont work well for MIMO, but a downtown setting with many buildings to create multipath will work better for MIMO. Less
