Abstract

Mobile radio communication systems are generally designed without taking into account the relative emitter/receiver phase dynamics. This paper formulates navigation and communication as aspects of an absolute phase estimation problem. Phase variations due to relative emitter/receiver motion are modeled as a third order Gauss-Markov process. Symbol-by-symbol detection and phase tracking are performed by a receiver open-loop structure consisting of a bank of stochastic ´matched´ nonlinear filters and a maximum a priori (MAP) decision algorithm. Simulation results, including low earth orbit (LEO) satellite communication, are presented showing the possibilities of the proposed approach
