Optimum Reception in an Impulsive Interference Environment--Part I: Coherent Detection

Abstract

Absfruct-In Part I, the relevant statistical properties of the recently developed statistical-physical model of generalized impulsive interfer- ence have been briefly reviewed (for sub Class A noise) and then ap- plied specifically to optimum coherent detection. It is shown that by using optimum and (locally optimum) detection algorithms (canoni- cally and explicitly derived), substantial savings in signal power and/or spectrum space cp be achieved for operation in these highly non- Gaussian interference environments. This paper (Part 11) extends the preceding analysis to cover various important cases of incoherent recep- tion. The same general model for narrow-band (Class A) impulsive inter- ference and interference examples used in Part I are again employed here. In addition to providing both canonical LOBD structures and ex- pressions for performance, this permits explicit quantitative compari- sons between coherent and incoherent reception for common classes of specific digital signal waveforms.
