APPARATUS FOR ULTRA-BROADBAND RADIO COMMUNICATION WITH HIGH NOISE-IMMUNITY Russian patent published in 2014 - IPC H04B7/00 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to radio engineering, particularly high-speed radio communication systems which employ short-wave (SW) pulsed ultra-broadband signals. The technical result is achieved by using an additional wavelet filter of an ultra-broadband signal and selecting SW ultra-broadband signals in the form of complex Morlet wavelet coefficients, a harmonic modulated by a Gaussian function from a received useful signal. The apparatus for ultra-broadband radio communication with high noise-immunity includes: a receive/transmit switch (3), an ultra-broadband filter (4), a switch (23), a band-pass filter (22), an antenna (5), a buffer device (1), a delay device (27), an ultra-broadband pulse generator (2), a clock pulse sequence generator (19), a broadband clock signal amplifier (20), ultra-broadband low-noise amplifier (6), an analogue-to-digital converter (25), a clock signal wavelet filter (26), a clock unit (18), an attenuator (7), an ultra-broadband signal wavelet filter (28), signal channel time slot device (9), a signal channel threshold device (10), a signal channel buffer device (11), a signal channel threshold voltage generator (12), a noise channel time slot device (13), a noise channel threshold device (14), a noise channel buffer device (15), a noise channel threshold voltage generator (16), a processing and control unit (17).

EFFECT: higher noise-immunity of receiving SW ultra-broadband pulses via an ultra-broadband channel in interference conditions at low signal-to-noise ratio values of at least 10-15 dB.
