Interference at a specific frequency will only affect the signal during a short interval. This is frequency hopping technique, where the users are made to change the frequencies of usage, from one to. If the PRN acts at the carrier-frequency level, this is the frequency - hopping form of spread spectrum (FHSS). Frequency Hopped Spread Spectrum FHSS.
