Phase-Shift keyed wideband signal against noises detection by quadrature receiver with input band-pass filter

G. S. Nakhmanson, G. A. Bakaeva

Abstract


In this paper we consider wideband signal against noise receiving by quadrature correlation receiver with input band-pass filter. We obtain analytical expressions of detection characteristics. We analyzed dependences of correct receiving on delay time, signal-to-noise ratio and input filter bandwidth. It is shown, that maximal probability of signal detection is obtained in case of non-zero delay time of received signal, which depends on filter bandwidth.
