Method for demodulating a carrier wave modulated by a digital symbol sequence

摘要

Method for demodulating a carrier wave modulated by a digital symbol sequence and transmitted via a noisy channel. According to the invention the ideal shapes of the edges of the possible transitions between two symbols are known and stored (reference edges). According to the invention, for the detection of a received and scanned edge the total scanning values are used to obtain the Euclidean distances to at least two reference edges and the reference edge with the shortest Euclidean distance is selected.
