Modelling and system identification for the inphase/quadrature process
Abstract
A realtime, sampleddata processing technique to combat both natural and intentional interferences on aeronautical radio communication and datalink channels was developed. The particular detection technique used is Integrated Detection, Estimation, and Identification (IDEI). It is assumed that the received data is in the stationary Inphase/Quadrature (IQ) form. The colored interference represents a jamming signal which is a Gaussian process. A modified diagonal transition matrix is used for the generating model. The closedform probability of error expression under imperfect identification is derived to analyze the sensitivity of detection error. The analysis and results of the probability of error of the IDEI detector are presented. The mathematical derivation and results for the Maximum Likelihood Identification of the stationary IQ process are presented.
