Abstract

Изобретение относится к передаче информации с помощью шумоподобных сигналов в сверхширокой полосе частот. Техническим результатом является повышение надежности связи, увеличение помехозащищенности и скрытности сигналов в канале связи. Назначают паре приемного и передающего устройств системы связи код шумоподобной несущей, модулируют последовательность коротких импульсов двоичной последовательностью информационного сообщения для получения последовательности разнополярных импульсов, формируют спектр последовательности разнополярных импульсов путем формирования на каждый импульс, в соответствии с его полярностью, прямой или инвертированной псевдослучайной последовательности (ПСП), соответствующей назначенному коду шумоподобной несущей, и излучают сформированный сигнал информационного сообщения на шумоподобной несущей. При приеме сигнала информационного сообщения на шумоподобной несущей анализируют помеховую обстановку в полосе рабочих частот, при наличии монохроматических помех на участках полосы рабочих частот режектируют помехи и осуществляют свертку очищенного от помех сигнала с назначенным кодом шумоподобной несущей и демодулируют выделенную последовательность разнополярных импульсов для получения информационного сигнала.The invention relates to the transmission of information using noise-like signals in the ultra-wide frequency band. The technical result is to increase the reliability of communication, increase the noise immunity and secrecy of signals in the communication channel. Assign a pair of noise-like carrier code to a pair of receiving and transmitting devices of the communication system, modulate a sequence of short pulses by a binary sequence of an information message to obtain a sequence of bipolar pulses, form the spectrum of a sequence of bipolar pulses by forming a direct or inverted pseudo-random sequence (CAP ) corresponding to the designated noise-like carrier code, and emit formed the information signal on the noise-like carrier. When receiving an information message signal on a noise-like carrier, the interference situation is analyzed in the operating frequency band, in the presence of monochromatic interference in parts of the operating frequency band, interference is rejected and the signal-assigned carrier-like noise code is convolved and the selected sequence of bipolar pulses is received to obtain an information signal.
