1. derive the least square solution 2. how to estimate variance based on the LS solution 3. a graph of RNN and asked me to explain it 4. an MDP question and asked me to compute the value function 5. compute the channel coherent bandwidth 6. estimation problem
OFDM, Fading Channel Model, BER, Modulation Schemes
List Maxwell's equations. I didn't have them memorized, so that didn't go too well.
OFDM Probability distributions for IID gaussian RVs. coherence time and coherence bandwidth
What is the SAR limit?
Edge trigger variation coding in RTL
how to beamform with X amount of antenna without the need of X amount of TRX chains
Can you turn big endian to little endian
Questions from past experience and wireless power designs.
They asked me to elaborate on some of my research/work experience and asked some fiddly programming questions.
