Receiver Operating Characteristics of Correlation Detection Systems Using 'OR' Circuits,
Abstract
A common problem in large multichannel correlation detection systems is the reduction of the data rate at the output of the detectors. This data rate reduction should be accomplished in such a way that performance is not too adversely affected. A simple technique that satisfies this requirement is to employ an 'OR' circuit. An 'OR' circuit is a multi-input, single-output device whose output is always the largest of the inputs. The main problem here is not the 'OR' circuits themselves but the performance of system in which they are employed. The performance measure used here is the receiver operating characteristic (ROC) curves. The ROC curves are the family of curves obtained from the parametric equations of detection probability and false alarm probability. The parameters are signal-to-noise ratio, threshold and number of inputs to the 'OR' circuit. These curves have been tabulated and are given in the two tables at the end of the memo. (Author)
