What is estimation in communication?
The purpose of estimation is to obtain an approximate value of an unknown parameter, based on observations made from measurements. The unknown parameter can for instance be a modulated information signal, the signal attenuation over a channel, the phase of a sinusoid, or the variance of the measurement noise.
What is detection in communication system?
detection, in electronics, the process of rectifying a radio wave and recovering any information superimposed on it; it is essentially the reverse of modulation (q.v.).
What is the difference between detection and estimation?
Detection: Decision between two (or a small number of) possible hypothesis to choose the best of the two hypothesis. Parameter Estimation: Given a set of observations and given an assumed probabilistic model, we get the best estimate of the parameters of the model.
What are the elements of detection theory?
Detection theory or signal detection theory is a means to measure the ability to differentiate between information-bearing patterns (called stimulus in living organisms, signal in machines) and random patterns that distract from the information (called noise, consisting of background stimuli and random activity of the ...
