Wideband digital communication system with spectral processing of noise waveforms

We propose a digital communication system on the basis of double spectral processing of ultra wideband (UWB) noise waveforms. The structure of the spectral modulator of UWB noise waveforms is presented for digital information transmission. The spectral modulator performs the code transformation of the UWB noise spectrum by means of simple delay lines. The basis of UWB noise waveforms having periodic spectral modulation is defined as the product of the frequency bandwidth and the duration of a binary information symbol. The spectral compression of UWB noise waveforms with an information rate is discussed. It is shown that digital communication systems with double spectral processing of UWB noise waveforms have a high immunity against electromagnetic interference. The excellent electromagnetic compatibility (EMC) and low probability of intercept (LPI) performance characterize the proposed digital communication system.
