ITU-R F.393-4-1982 Allowable Noise Power in the Hypothetical Reference Circuit for Radio-Relay Systems for Telephony Using Frequency-Division Multiplex - Section 9A - Performance Objectives, Propagation and Interference Effects
that the total noise power in a radio-relay system is dependent on the one hand upon a number of factors concerned with equipment design, and on the other hand upon the path attenuation and the variation of path attenuation with time, which are in turn de
