STANDARDIZED SET OF TEST CONDITIONS AND MEASUREMENT PROCEDURES FOR THE SUBJECTIVE AND OBJECTIVE DETERMINATION OF PROTECTION RATIOS FOR TELEVISION IN THE TERRESTRIAL BROADCASTING AND THE BROADCASTING-SATELLITE SERVICES
The protection ratio is the minimum value of the wanted-to-unwanted signal ratio,usually expressed in decibels, at the receiver input determined under specified conditions such that a specified reception quality of the wanted signal is achieved at the receiver output (Note 1).The protection ratio is useful in planning and operations where multiple transmissions require frequency and orbit sharing between similar or dissimilar transmissions.
