Reed Solomon Coding for Frequency Hopping Spread Spectrum in Jamming Environment
Frequency hopping spread spectrum with noncoherent M-ary frequency shift keying system is considered. In this study Reed Solomon codes RS (255, 223) are employed in a standard error correction role to provide some Anti-Jamming (AJ) capability with 8-bit symbols. Noise has been added to RS encoded data, which is demodulated at RS decoder perfectly. Matlab simulations have been implemented for nu...
متن کاملPerformance of Reed-Solomon Coded Frequency-Hop Spread-Spectrum Communications in Partial-Band Interference
This paper is concerned with the performance of a Communications system which utilizes frequency-hop spread spectrum, diversity transmission, Reed-Solomon coding, and parallel error-correction and erasure-correction decoding. Both binary signaling and M-ary orthogonal signaling are considered. The goals are twofold. First, it is desirable to provide good performance in partial-band Gaussian noi...
متن کاملAn Interpolated Frequency-Hopping Spread-Spectrum Transceiver
A technique of spread-spectrum transmission, interpolated frequency-hopping (IFH), is presented. IFH employs a carrier that moves smoothly and continuously in frequency, helping to alleviate problems, such as spectral splatter and transient mismatch, which are a concern in conventional phase-locked loop (PLL)-based frequency-hopping spread-spectrum systems. In IFH, the pseudorandom hopping code...
متن کاملPerformance Analyses of Fast Frequency Hopping Spread Spectrum and Jamming Systems
As technology becomes increasingly able to meet the requirements, interest in faster, noncoherent, frequency hopping rates to reduce the jamming of communication has heightened. The focus of this paper is on the performance of the fast frequency hopping spread spectrum system operating in the presence of partial band noise jamming. In this paper we consider a communication system that transmits...
متن کاملSignal Anti-Jamming Through Encrypted Spreading Codes Based On Frequency Hopping Spread Spectrum
Now a days is fully digitalized time and communication is the one of the most important part in our modern life [1]. Everywhere digital system are present like railway, radar, satellite, missile launchers, GPS, Wi-Fi, radio transmission, cellular mobile communication, vehicles, sensors, etc. digital signal play very important role in digital communication system for assessment of signal securit...
