RADIO FREQUENCY MODULATION METHOD Russian patent published in 2024 - IPC H04L27/32 

FIELD: wireless communication systems; digital communication technology.

SUBSTANCE: result is provided due to the fact that the output register of the digital information source is conditionally divided into a number of connected K n-bit units, information from which is transmitted to the antenna unit of the transmitter, having n parallel-connected output stages. Each of the n-bit units K_i=N/n, where N is the capacity of the output register, an is the number of synthesizer frequencies, which coincides with the number of bits of each of the K_i units and the number n of output stages. Each of K_i n-bit units has its own amplitude of output pulses, and all similar bits of each K_i unit are connected to each other. This allows summing the output signals of each of them at one of the frequencies. Discharges are also connected to each of the n output units of the transmitter, and each of the n frequencies coming from the switch is supplied to the output units, creating n! combinations of frequencies, wherein a plurality of signals B is formed as B = n!mⁿ, where m is a possible number of amplitudes obtained in each of n output stages as a result of summation of signals of like digits.

EFFECT: high noise-immunity of the system, wider message alphabet and simple radio signal modulation scheme.
