ECE 531: Detection and Estimation Theory
ece 531 : Detection and Estimation Theory Natasha Devroye ~devroye Spring 2011. Example of Detection Example of Estimation Goals infer value of unknown state of nature based on noisy observations Mathematically, optimally Noise Transmission /. Nature Processing measurement phenomenon model of observation decision rule experiment or transmission Estimation function process the ``truth''. mapping from observation space model of hypothesis H to decisions/. estimates Detection example 1: digital communications Noise Source Encoder Channel Decoder Destination 10001010100010. Detect? Detection example 2: Radar communication Send Receive Hypothesis Detect?
