DETECTION OF AN ULTRA-WIDEBAND QUASI-RADIO SIGNAL WITH UNKNOWN ARRIVAL TIME AGAINST THE BACKGROUND OF WHITE NOISE

摘要

We synthesize and analyze the maximum-likely detector of an ultra-wideband quasi-radio signal whose duration can be several periods or even a part of the period of harmonic oscillation with unknown amplitude, phase, and arrival time. Characteristics of the classical quadrature detector during reception of an ultra-wideband quasi-radio signal are found. The results of statistical simulation of detection algorithms are presented.
