METHOD FOR ERROR-PROTECTED DATA TRANSMISSION, METHOD FOR ERROR-PROTECTED DATA RECEPTION, AND DATA TRANSMISSION SYSTEM Russian patent published in 2002 - IPC

FIELD: error-protected data transmission and reception. SUBSTANCE: data are transmitted by means of signal using set of simultaneously active modulated frequency channels, These data are encoded by means of error-protecting code. Sequential data sections are disposed with pseudorandom dependence in different frequency channels which prevents attenuation occurring in frequency channels periodically spaced apart. Pseudorandom arrangement is implemented by entering data sections in memory device in one order and their reading out of memory in other order. In this way sequential signals are modulated. Memory location is emptied in reading to modulate one signal and is filled up with data sections intended for modulating sequential signal. This is made by interchanging order of memory locations wherein data sections are entered for each next signal. EFFECT: enhanced reliability of data protection from errors in transmission and reception. 28 cl, 5 dwg
