Key Terms

Spatial correlation: A correlation between a signal's spatial direction and the average received signal gain between two observed nodes.
Angle spread: The observed angle of an attacking node upon the link signature (LS) between a transmitter receiver (T,R) pair.
Link correlation: The correlation of attacking nodes LS (Eve) of with that of the LS between (T,R) (Bob & Alice).
Channel characteristics: Additional information of (T,R) pairs such as time, gain, distance, etc…

Day 1

Finish testing all the ML methods that we have and do some comparisons between them to see which method takes the least amount of guesses

Day 2

Lecture based on different aspect to approach in terms of new algorithm

Day 3

Focus on two ideas/approach

Modifying the kernel Function for better result
Finding correlation of wireless channel using distance and angle spread

Day 4

Get the distance of each channel and begin implementing their angle in correspond to the transmitter and receiver been pass in for a single or multi target

Day 5

Continuing implementation…
