METHOD FOR INCREASE OF INFORMATION CAPACITY OF TRANSMISSION SYSTEM BASED ON PULSE CODE GROUP IN COMMUNICATION NETWORKS

摘要

A method for increase of informative capacity of transmission systems based on pulse code groups in communication networks comprises modulation of pulses thereof. If information is transmitted by code groups, every pulse of said group is subject to particular simultaneous or separate modulation by amplitude, width or polarity. Each modulated pulse of the group represents a block of N-bit, proportional to number of combinations and gradations of said parameters. Estimation of said modulation parameters of each pulse is made on the receiving side, according to which for each pulse the bit block correspondent to the modulated one is restored.
