Question

With reference to satellite communication, the anti-jamming technique preferred is select one:

a. Key leverage

b. Frequency hopping

c. Once-only key

d. Frequency-spectrum modulation

Answer 1

Frequency -spectrum modulation

Answer 2

With reference to satellite communication, the anti-jamming approach desired is Frequency hopping :

Explanation:

• Frequency-hopping spread spectrum (FHSS) is a technique of transmitting radio signals through hastily converting the carrier frequency amongst many distinct frequencies occupying a huge spectral band.
• The available frequency band is split into smaller sub-bands.
• Signals hastily change ("hop") their provider frequencies the various middle frequencies of those sub-bands in a predetermined order.
• Interference at a selected frequency will have an effect on the sign only all through a quick interval.

Frequency Hopping is the correct option.
