Hello
Currently wi-fi and mobile networks are operating on wave inversions that occur 8 times in every single wave.
GPS uses a wave inversion that occurs on one wave every 1538 waves, which is the length of each PRN bit. These waves are 190 mm long, so with a consumer grade error of +/- 3 metres it is taking the receiver 15 waves to notice that the inversion has occurred, and the best non-RTK receivers, with 1 metre accuracy, are taking 5 full waves before they notice the inversion has occurred.
Can anyone advise the technical details, or any books/articles on such, and what recent advances are occurring in this area?
I take it that something as simple as utilizing 2 channels, one generating a wave on the base frequency and alignment and the other generating a 180° offset wave (inverted), has been tried and doesn't lower the number of waves required to identify the inversion but I would appreciate technical understanding
Thanks for your time
Glenn
