Unformatted text preview: Detection and Estimation (Spring, 2009) Introduction NCTU EE P.1 Introduction Detection theory involves making a choice over some countable (usually finite) set of options; while estimation involves making a choice over a continuum of options. ~ Detection and Estimation in Signal Processing To decide the occurrence of an event (detection) and then to determine more information about that event (estimation). y Radar: determine the position of an aircraft Received signal is embedded in noise Binary hypothesis testing problem. Detection & Estimation (Spring, 2009) Introduction NCTU EE P.2 y Sonar: determine the existence and position of a target Estimate the bearing of the target based on the noise radiated by the target. y Speech Speech recognition: e.g., to discern among the digits “0”, “1”, …, “9”. Multiple hypothesis testing problem. Detection & Estimation (Spring, 2009) Introduction NCTU EE P.3 To extract attributes that are less susceptible to variation ⇒ Linear Predictive Coding (LPC) Detection & Estimation (Spring, 2009) Introduction NCTU EE P.4 y Image Analysis: estimate the position and orientation of an object in an image. y Biomedicine: estimate the heart rate. y Communications: estimate the carrier frequency of a signal so that the signal can be demodulated to baseband....
