Abstract
In this paper, we present the experimental impulse-radio transmission based on spectral modulation technique aimed at improving the energy efficiency, noise immunity and interception security of high-speed Radio-over-Fiber communication systems. The proposed modulation method is based on frequency-shift keying of three wideband solitonshape pulses with central frequency hopping in the desired frequency range. Mathematical and simulation models for the modulation and symbol coding techniques are provided. The system performance was evaluated through experimental BER measurement on the basis of the ultra-wideband laboratory test bench under the strict regulations of the SCRF spectral emission mask for ultra-wideband systems in Russia. A comparison of the obtained results with the current record of impulse-radio transmission under the SCRF spectral mask showed that the proposed spectral modulation method provides less achievable wireless transmission distance, however gaining into interception security of the link. Nevertheless, the employment of the improved decoding technique can fix this disadvantage. The achieved results demonstrate the application viability of the proposed method in high-speed Radio-over-Fiber communication systems.
