MAPdekodning
MAPdekoding, short for maximum a posteriori decoding, is a method used in digital communications and coding theory to estimate transmitted data from a received signal. The goal is to choose the transmitted sequence that is most probable given what was received, using both the channel model and any prior information about the data.
Formally, MAP decoding selects the transmitted symbol sequence X that maximizes the posterior probability P(X|Y), where
MAP decoding is implemented in practice through algorithms that compute or approximate the posterior probabilities for
MAP decoding is widely used in wireless and data communication systems to achieve improved error performance,
