BROADBAND TRANSCEIVER WITH SOFTWARE PROGRAMMABLE RESETTING FOR THE PHASE SIGNAL Russian patent published in 2018 - IPC H04L7/06 

FIELD: radio engineering and communications.

SUBSTANCE: invention refers to the field of wireless communication, in particular to digital radio communication, and is intended for use in the information transmission systems by means of interference-proof signals with multiphase manipulation. Broadband transceiver consists of the transmitting and receiving part, in addition to the transmitting part of the device, the phase shift control unit (4) is introduced, the information input of which is connected to the output of the high-frequency switch (3), and the control inputs are connected to the corresponding outputs of the decoder (6). Input of the decoder (6) is connected to the output of the pseudo-random sequence generator (7), the output of the phase shift control unit (4) is connected to the first input of the frequency mixer (5). Phase shift control unit (24), the information input of which is connected to the output of the mixer (23), was additionally introduced in the receiving part of the device, and the control inputs are connected to the corresponding outputs of the decoder (22), the input of which is connected to the output of the pseudo-random sequence generator (18), and the output of the phase shift control unit (24) is connected to the input of the intermediate frequency amplifier (25).

EFFECT: technical result consists in increasing the noise immunity of the generated radio signal under the influence of imitation interference due to the pseudo-random phase change of the signal.
