FIELD: radio communications. SUBSTANCE: newly introduced in transmitting part of broadband-signal communication system are inverse Fourier transform unit, first buffer register, first tunable frequency synthesizer, and second band filter; introduced in receiving part of system are demodulator, forward Fourier transform unit, second buffer register, second tunable frequency synthesizer, and noise spike detection and rejection unit. EFFECT: enhanced narrow-band noise immunity in receiving broadband signals. 1 cl, 3 dwg |
