Part 1 of this paper [Appl. Opt. 14, 666 (1975)] dealt with the cw radar and analog communications uses of three-frequency nonlinear heterodyne detection. In this paper, we evaluate the technique for a number of specific pulsed radar and digital communications applications. Both the vacuum channel and the lognormal turbulent atmospheric channel are considered. It is found that the advantages of the technique in the pulsed/digital system are similar to those obtained in the cw/analog system. Computer generated error probability curves as a function of the input signal-to-noise ratio are presented for a variety of binary receiver parameters and configurations and for various levels of atmospheric turbulence. Orthogonal and nonorthogonal signaling schemes, as well as dependent and independent fading, are considered. When Doppler information is poor, performance is generally superior to that of the conventional heterodyne system.read more

Multiphoton optical heterodyne detection
TL;DR: In this article, the authors examined the behavior of a multiphoton absorption heterodyne receiver and obtained an expression for the detector response, signal-to-noise ratio (SNR), and minimum detectable power for a number of cases of interest.

Nonlinear Heterodyne Detection
TL;DR: In this article, the performance and requirements of a number of alternative heterodyne receiver configurations were studied, and two basic systems which are intrinsically nonlinear, the first by virtue of the multiple-quantum detection process itself, and the second by consequence of the mixing configuration and the electronics following the detector.

Malvin C. Teich,Rainfield Y. Yen +1 more
TL;DR: The technique, which is similar in principle to heterodyne radiometry, makes use of a two-frequency transmitter and a nonlinear second detector and is particularly useful for signal acquisition; for signals of unknown Doppler shift, performance is generally superior to that of the conventional system.

An introduction to the theory of random signals and noise
TL;DR: The aim of this book is to clarify the role of noise in the development of linear and nonlinear systems and to provide a procedure forormalising the noise generated by these systems.
