The Impact of Interference on GNSS Receiver Observables – A Running Digital Sum Based Simple Jammer Detector
This paper proposes a multilevel Return-to-Zero (RZ) coding technique for the transmission of digital signals. The Multilevel Technique presented here helps in removing certain problems associated with Bipolar and Manchester coding techniques. This multilevel technique utilizes different D.C. levels for representing a ‘0’ and ‘1’ with a RZ method. The PSD (power spectral density) of the encoded signal is analyzed and possible generation method is also proposed.
