METHOD OF DIRECT AND REVERSE DATA TRANSMISSION AND RECEIPTION Russian patent published in 2008 - IPC H04B3/04 

FIELD: radio engineering.

SUBSTANCE: invention refers to communication engineering and can be used as direct and reverse data transmission and reception method trough digital communication. Technical result is obtained by that information sources on direct and reverse transmitting sides, if required, is formatted with multiplexing of binary digital streams (BDS) in interpolator, e.g. with time division and modulated in high-frequency modulators, transformed to signal flow. Inversely signal flows on receiving side are demodulated in high-frequency demodulators. Signal flows are transformed to multiplexed BDS flows, demultiplexed in corresponding demultiplexers, formatted, if required, and supplied to information consumers. If required on transmitting sides the signal flows of the other information source groups are summed and divided in multiple access units on receiving sides. Demultiplexer connected in front of modulator direct only including additionally, reads BDS ordered binary digits x_k synchronously per cycle where K_n is information sources number. x_k is multiplied to positive numbers a_k which are calculated e.g. from high-increasing numbers applying Merckle-Hellman circuit. Values a_kx_k are summed to receive digital symbol flow introduced accordingly after demultiplex demodulator. Synchronous digital symbol flow S_n is transformed according to Merckle-Hellman circuit to digital symbol flow is transformed according to relation if x_i=1, if where i=K_n-1, K_n-2,... 1, and x_i=0 in other cases, in BDS which are supplied in order, as well as at said reading, to outputs of demultiplexer.

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