DIRECT AND REVERSE INFORMATION TRANSMISSION AND RECEPTION SYSTEM Russian patent published in 2008 - IPC H04B7/00 

FIELD: radio engineering.

SUBSTANCE: invention refers to communication engineering and can be used as direct and reverse data transmission and reception system (DTRS) from information source to consumers using digital data communication. Technical result is obtained by that DTRS contains direct and reverse series functionally connected heterogeneous information sources, interpolator, e.g. with time division, of binary digital streams (BDS), high-frequency signal modulator with carrier frequency generator, transmitter, receiver, high-frequency signal demodulator, digital stream to BDS demultiplexer of information consumers and, if necessary, formatting and multiple access units, e.g. with code division. DTRS contains provided in front of modulator direct only, including additionally, interpolator generating ordered BDS synchronous per binary digit multiplied to positive numbers formed e.g. from high-increasing numbers applying Merckle-Hellman circuit, and summed to receive digital symbol flow. Demodulator is followed with demultiplexer transforming ordered digital symbol flow synchronous per binary digit in processor according to Merckle-Hellman circuit to digital symbol flow thereafter transformed.

EFFECT: higher performance of frequency resource, simplified solution for EMC support, eg of short-range radio navigation systems and GSM-900 networks.
