Super interesting! But I feel like there is a bit of a conclusion missing for me.
So 1500 Photons hit the receiver per bit send, but this is obviously way to few to keep processing the signal and it will just be drowned out by noise? Where do we go from here? Does voyager repeat its signal gazillions of times so we can average out the noise on our end? Where can I find more information on what is done with these few photons?
- SonOfLilit 2y agoNo, those 1500 photons are enough and we basically read the signal from them, from my reading of the comments here.
- djha-skin 2y agoLook up Solomon Reed erasure coding. Voyager uses it, so does qrp Ham radio operators.
