METHOD FOR DETERMINING THE PROBABILITY OF FAILURE AND RELIABILITY FOR RADIO RADIO arbitrary frequency

摘要

A method for determining the probability of errors and radio reliability for an arbitrary frequency ionospheric radio channel upon receipt of short continuous linear-frequency-modulated signal, comprising the steps of that signal at the receiver output A (t) is divided into signal and noise components, parameter estimation which allows to calculate the characteristics of the communication quality in the radio channel, characterized in that the signal a (t), prior to separation at the signal and noise components are isolated and attenuated noise concentrated (To form a list of radio channels occupied lumped noise), which increases the probability of correctly separating A (t) signal at the signal and noise components and reliable estimation of their parameters, and in that the determination of the probability of bit error for any frequency ionospheric radio channel with a working frequency ƒproiskhodit estimated in the time domain, after separation of the signal and noise components by filtering using bandpass filters, and estimation of their average continuous time dependences m oschnostey P (t) and P (t) by formulamgde- frequency dependence of the signal / noise ƒi- initial frequency and rate of frequency adjustment linearly frequency modulated signal, respectively, for Rayleigh radio channel and wherein β (ƒ) - frequency dependence of the power ratio and regular fluctuation component signal P (t) for the case kvazireleevskogo channel further radio frequency dependence of reliability in the band Δƒdlya predetermined permissible error probability rnahoditsya not the formulas, assuming a certain law disintegrations
