Analysis of the Causes of Energy Losses During Processing of Signals with Frequency-Selective Fading and Intersymbol Interference

The analysis of the mutual influence of energy losses during processing of signals with frequency-selective fading and intersymbol interference has been carried out. It has been shown that the known expressions for estimating the signal/noise ratio at the output of the scheme of noncoherent processing of signals with frequency-selective fading and intersymbol interference can be adjusted to separately account for the contribution of these phenomena that have different physical meaning. The resulting expression for the estimation of power losses in noncoherent processing of signals with intersymbol interference has been obtained.
