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

FIELD: wireless communication equipment.

SUBSTANCE: invention relates to wireless communication systems and specifically to digital communication technology. Such a result is ensured by emitting digital signals in the form of radio waves through n output stages, to each of which one of n frequencies is transmitted from the frequency synthesizer for broadcasting messages from a plurality of digital messages B through an antenna unit containing n antennas. At that, the output register of the digital information source is conditionally divided into a number of series-connected n-bit units K1, K2, K3, information from which is transmitted to the antenna unit of the transmitter, having n parallel output stages, each of which emits signals at its own frequency. Each of the blocks 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 blocks. In addition, all like bits of each of the K_i unit are connected to each other, and also connected to each of the n like output units of the transmitter, wherein the number of the emitted frequency coincides with the number of the corresponding bit of each K_i unit connected to it, wherein the plurality of signals B is generated as B = mⁿ, where m is the possible number of amplitudes obtained in each of the n output stages.

EFFECT: high noise immunity of the system and simple modulation of radio signals.
