WebSep 16, 2006 · In 1960s Shiryaev developed Bayesian theory of change detection in independent and identically distributed (i.i.d.) sequences. In Shiryaev's classical setting the goal is to minimize an average detection delay under the constraint imposed on the average probability of false alarm. Recently, Tartakovsky and Veeravalli (2005) developed a … Webalpha The false alarm probability used. sig.level Powers > sig.level can be considered significant peaks at p=alpha. peak The maximum power in the frequency/period interval inspected. peak.at The frequency/period at which the maximum peak occurred. p.value The probability that the maximum peak occurred by chance. Note
WebBy inspecting the graph with the data cursor, you can see that to achieve a probability of detection of 0.9, you must tolerate a false-alarm probability of up to 0.05. Without using phase information, you will need a … WebMeasuring the probability of erroneous detection is defined in TS36.104, Section 8.4.1 [ 1]. The target defined for any bandwidth, all frame structures and for any number of receive antennas is a false alarm probability less than or equal to 0.1%. The input to the PRACH detector is made up exclusively of a Gaussian noise signal.
