# Short Presentation on current status (Beacon)
|
||||
|
||||
Mostly to show what I've been doing uptil now.
|
||||
|
||||
Recap Sine Beacon
|
||||
DTFT
|
||||
Deviation Minimisation was poorly explained (and doesn't work)
|
||||
|
||||
!! 150MHz in addition to 50MHz simulation
|
||||
|
||||
Maybe Pulsed beacon scheme if time allows
