The influence of frequency hopping spread spectrum on probability of collisions in asynchronous radio system with frequency instability of the carrier

There are obtained results of investigations of the FHSS on the probability of collisions in an asynchronous radio system without feedback with frequency instability of the carrier commensurate with the band of signal. It is shown that FHSS is inappropriate for reduce the probability of collisions with frequency instability of the carrier commensurate with the width of spectrum signal for normalized width power spectral density d <;1.
