The probability of error for Frequency Hopping Spread Spectrum in Wireless Communication Using MFSK Modulations
-The paper is focus on the performance of fast frequency hopped spread spectrum by using M-ary frequency shift keying (MFSK) modulations. In fast FH systems, the frequency-hop rate Rh is some multiple of the symbol rate. Basically, each (M-ary) symbol interval is subdivided into N subintervals, which are called chips and one of M frequencies is transmitted in each subinterval. The probability o...
متن کاملPerformance Improvement of Wireless Communications Using Frequency Hopping Spread Spectrum
To improve the performance of short-range wireless communications, channel quality must be improved by avoiding interference and multi-path fading. Frequency hopping spread spectrum (FHSS) is a transmission technique where the carrier hops from frequency to frequency. For frequency hopping a mechanism must be designed so that the data can be transmitted in a clear channel and avoid congested ch...
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 کاملSpread spectrum audio watermarking using frequency hopping and attack characterization
In this paper, we present a novel audio watermarking scheme that uses attack characterization to obtain high robustness against standard watermark attacks. The watermark embedding and detection are based on the frequency hopping method in the spectral domain. Perceptual transparency of the algorithm, achieved using frequency masking property of the human auditory system, was con5rmed throughout...
متن کاملLow Probability of Intercept Frequency Hopping Signal Characterization Comparison using the Spectrogram and the
Low probability of intercept radar signals, which are often problematic to detect and characterize, have as their goal ‘to see and not be seen’. Digital intercept receivers are currently moving away from Fourier-based analysis and towards classical time-frequency analysis techniques for the purpose of analyzing these low probability of intercept radar signals. This paper presents the novel appr...
