METHOD FOE DETERMINATION OF DISTORTION FACTORS OF ANALOGUE MICROWAVE LINK TO PARAMETERS OF DIGIT STEAM TRANSMITTED OVER MICROWAVE LINK WITH COMPOSITE MODULATION

摘要

.A method for determination of degree of influence of analogue microwave link to parameters of a digit steam, which are transmitted over a microwave link with composite modulation comprises the measuring communication channel noise immunity as a ratio of signal power/ power noise in receiver input. Using standard methods, the measured value of noise immunity is subtracted from calculated value of microwave link noise immunity in the Gaussian channel with thermal noise influence.
