METHOD OF INFORMATION TRANSMISSION USING MIMO SCHEME IN HYPERCOMPLEX SPACE Russian patent published in 2023 - IPC H04B7/413 

FIELD: radio engineering.

SUBSTANCE: in the method of transmitting information using the MIMO scheme in N=2ⁿ, n=2, 3, 4 hypercomplex space, sequences of binary data pulses consisting of zeros and ones arriving at the input of the transmitting device are converted into bipolar pulses, which are converted into N -dimensional information vector consisting of N information pulses and forming a hypercomplex number in a vector representation, while modulation on the transmitting side is carried out by multiplying the information vector by a hypercomplex carrier, which is a hypercomplex number in polar form with different N-1 reference frequencies in a matrix representation and acting as a channel matrix MIMO channel, while the multi-frequency channel matrix MIMO is decomposed into the sum of single-frequency matrices, which are modulated separately and their results are added up, forming multi-frequency elements of an N-dimensional vector, while the phase-modulated elements of the output multi-frequency modulated vector are transmitted sequentially in time either with code division or with frequency division, while the signal vectors are coherently demodulated by multiplying the received vector by transposed basis matrices of single-frequency matrices representing an orthogonal basis, and the reception of the signal vector arriving at the receiver input is carried out using the integration of the results of the multiplication followed by addition for each single-frequency matrix of the orthogonal basis and making a decision in the decision device about the value of the vector elements, while the hypercomplex carrier is a hypercomplex number in polar form and in matrix representation in the form of a square NxN matrix with N-1 reference frequencies, combinations of which form 2^N-2 combinational frequencies, and the same number of single-frequency matrices.

EFFECT: increased noise immunity and information transmission rate in wireless and wired communication systems.
