METHOD OF GENERATING COMPOSITE QUASIOPTIMAL SIGNALS AND DEVICE FOR REALISING SAID METHOD Russian patent published in 2010 - IPC H03H17/00 

FIELD: physics; radio.

SUBSTANCE: invention relates to radio engineering and can be used in space command radio links. The technical outcome of the invention is increased noise immunity of signals, simplification and increased reliability of error-correction decoding. The method of generating composite quasioptimal signals involves converting binary information into a series of n steps distinguished by generated signals. Information is propagated in each step for generating pseudonoise codes of the composite quasioptimal signal by synchronously generated clock pulses. The device for generating composite quasioptimal signals includes a series of n steps, each of which is distinguished by generated signals. Each step includes data inputs "1" and "0", an i^th pseudonoise code generator, first, second, third and fourth AND components, as well as first and second OR components connected to each other.

EFFECT: use of composite pseudonoise signals with high noise immunity to transmit information in space radio links, with optimal processing at the receiving side using a cascade of discrete matched filters.
