METHOD FOR RADIO COMMUNICATION WITH MULTIPLE ACCESS Russian patent published in 2010 - IPC H04B7/204 

FIELD: electric engineering.

SUBSTANCE: in method at transmitting side non-linear first and second pseudorandom sequences (PRS) are modulated by according bipolar binary first and second information sequences (IS), in binary third IS bipolar pulses are transformed into unipolar ones, multiplied by elements of the first Walsh code, and inverted pulses of the third IS - by elements of the second Walsh code, results of multiplications are combined and multiplied by modulated second PRS; result of this multiplication is used to modulate bearing oscillation, producing wideband vector phase-manipulated signal, elements of which are transmitted into communication channel at orthogonal polarisations under control of the first modulated PRS; at receiving side copy of the first PRS and its inversion is used to match polarisation conditions (PC) of elements in vector reference signals with PC of elements in vector useful signal, which bears symbols of three IS, result of multiplication of the second PRS copy to copies of the first and second Walsh codes is used to modulate copy of bearing oscillation, producing scalar reference signals for correlation processing of useful signal to extract information units and zeros in the first, second and third IS in four signal channels in compliance with recovery table, erroneous symbols are erased, result of multiplication of scalar reference signals with pulses of meander type are used to compensate signal-like noise.

EFFECT: improved throughput capacity and number of subscribers in systems with multiple access, and compensation of signal-like noise and erasure of erroneous symbols in case of high polarisation distortions of signals.
