In many detection applications, the signal to be detected, referred to as target signal, is not directly available. A reference channel (RC) is often deployed to collect a noisecontaminated version of the target signal to serve as a reference, which is then used to assist detecting the presence/absence of the target signal in a test channel (TC). A standard approach is to cross-correlate (CC) the signals received in the TC and RC, respectively. When the signal-to-noise ratio (SNR) in the RC is… CONTINUE READING
