High Frequency (HF) Amplitude Modulation (AM) Signal-to-Interference Ratio (SIR) Study,

Abstract

The objectives of this study are to determine reasonable S/I ratios for high frequency audio modulation (HF AM) Navy Tactical communications, to compare these ratios with current International Frequency Registration Board (IFRB) specifications, and to determine the effects of modifying the SIR's. The approach taken was to develop a mathematical model capable of relating signal, noise, interference and probability of achieving required Signal-to-Noise Ratios (SNR's) and Signal-to-interference Ratios (SIR's).
