Summary:
This paper demonstrates the execution and performance of frequency hopping spread spectrum (FHSS) in hostile jamming surroundings as correspond to conventional system. The system in this paper is confined to the merest assessments establish on the power ratio between the signal and entire interference. In scheming an antijam FHSS system, the spread bandwidth, , is by and large fixed at the start, and repeatedly with the usable bandwidth. Two rectangular bandpass signals have been diagrammed and the observance matrices are incurred by adding signal to jammer, arranging the jammer amplitude at 6 with matched filter output. From the simulation results it has revealed that plain signal is entirely masked by the jammer and is not noticeably ascertained at the filter output, the FHSS is the one, time constricted by the matched filter, is evident uniquely.
