SPACE-DIVISION RADIO LINK Russian patent published in 2004 - IPC

FIELD: radio communications; digital data transmission.

SUBSTANCE: proposed radio link that can be used for communications with mobile objects and for reverse duplex radio control channels, as well as for burst transfer radio networks during on-line instruction communications in unprotected regions has on sending end carrier and clock frequency generator 1, orthogonal pseudorandom sequence shaper 2, pseudorandom sequence generator 3, phasing unit 4, multipliers 5, 6, addition unit 9, 90⁰ phase shifter 7, phase keyer 8, power splitter 19, power amplifiers 20, 21, and transmitting antenna feeds 22, 23. On receiving end it has synchronizer 15, multipliers 10, 11, orthogonal pseudorandom sequence shaper 12, reference pseudorandom sequence generator 13, phasing unit 14, band filters 16, 17, phase detector 18, adder 28, amplitude limiter 29, and receiving antenna feeds 25, 26.

EFFECT: enhanced noise immunity of data transferred during its doubling with aid of orthogonally polarized signals.
