An 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 کاملImplementation of a Fast Frequency Hopping Spread Spectrum modulator with System Generator on a FPGA
This work is based on a previous FFHSS (Fast Frequency Hopping Spread Spectrum) transceiver designed for wireless optical communications. The core of the transmitter is a discrete DDS (Direct Digital Synthesizer). In the first prototype the DDS control and the digital synchronization signal were generated using a PLD (Programmable Logic Device), besides a discrete external filter was necessary ...
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 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...
