METHOD FOR TRANSMITTING INFORMATION USING ULTRAVIOLET RANGE Russian patent published in 2021 - IPC H04B10/00 

FIELD: communication.

SUBSTANCE: invention relates to communication equipment and can be used in systems using the ultraviolet range for transmitting encoded digital information between subscriber devices, including that in the "radio silence" mode. To realise the technical result, two channel sequences are formed, wherefor the transmitted data in form of an informational bit sequence is distributed between two channels of the transmitter. In the first channel, a pre-formed pseudo-random M-sequence No. 1 is assigned to the element of the channel sequence assuming the value "1", and a pre-formed pseudo-random M-sequence No. 2 is assigned to the element of the channel sequence assuming the value "0". In the first channel, a pre-formed pseudo-random M-sequence No. 3 is assigned to the element of the channel sequence assuming the value "1", and a pre-formed pseudo-random M-sequence No. 4 is assigned to the element of the channel sequence assuming the value "0". Frequency-pulse modulation of the group multilevel signal is executed in the modulator, selecting the duration of pulses based on the fact that the higher the transmission distance, the longer the duration of the transmitted information pulses using the ultraviolet range.

EFFECT: increasing the data transmission rate and the spectral efficiency of the described communication systems.
