RADIO LINK Russian patent published in 2004 - IPC

FIELD: radio engineering.

SUBSTANCE: radio link that can be used in radio channels to transfer information when communicating with mobile objects and also in reverse duplex radio control channels and burst radio networks to transfer on-line instructions in unprotected regions has on sending end carrier and clock frequency generator 1, first orthogonal pseudorandom sequence shaper 2, first pseudorandom sequence generator 3, first phasing unit 4, first and second multipliers 5, 6, 90⁰ phase shifter 7, phase keyer 8, addition unit 9, single pulse generator 19, multitapped delay line 20, inverters 21₁, 21₂, 21₃, adder 22, and balance modulator 23. On receiving end it has third and fourth multipliers 10, 11, second orthogonal pseudorandom sequence shaper 12, second pseudorandom sequence generator 13, second phasing unit 14, band filters 16, 17, 25, phase detector 18, and correlator 24.

EFFECT: enhanced reliability of hiding information transferred.
