METHOD FOR QUASI-SYNCHRONOUS MULTIPLE ACCESS WITH CODE SEPARATION BASED ON CLOCK FREQUENCY SYNCHRONIZATION CONDITIONS Russian patent published in 2023 - IPC H04W56/00 

FIELD: communication technology.

SUBSTANCE: invention relates to communication technology and can be used in satellite communication systems. Based on the clock frequency synchronization conditions with an open radio channel, many transmitting stations share energy resources to transmit signals via the CDMA transmission mode with an extended spectrum; with the help of an external guiding signal, clock frequency synchronization is provided for CDMA signals transmitted by a plurality of terminal stations in an open radio channel and the difference between delays in signal propagation from a plurality of terminal stations to a relay node or receiving station is eliminated, so that a plurality of CDMA signals received by a relay node or receiving station are synchronized in clock frequency and phase-matched, providing quasi-synchronous reception of multiple CDMA signals.

EFFECT: ensuring the operation of CDMA in quasi-synchronous conditions in channels with a relay node and without a relay node.
