Synchronization of all constituent units must be provided in all DDTS with a serial synchronous interface, primarily of encoding and decoding devices. This work investigates the method and algorithms of information reception and transmission based on using of code signal feature that do not require the application of error-correcting codes and special measures for synchronization ensuring. Special feature of the developed algorithms is the representation of each discharge symbol of the primary error-correcting code in the form of pulse sequences – series of pulses conditionally infinitely small duration rigidly interconnected by fixed time intervals that are multiple to certain time delay Δt. The paper shows that the suggested method of transmission has the properties of self-synchronization, and significantly increases the information reliability of the system.
