TELEMETERING INFORMATION TRANSMISSION METHOD Russian patent published in 2020 - IPC G08C19/28 

FIELD: data transmission systems.

SUBSTANCE: code sequences filling time gaps allocated for transmission of initial bits of transmitted information are formed as consisting of components represented by code segments, which by their position in the measurement word are lower (a_mni) and upper (a_sni) half of words. Then, from two semi-words a_mni and a_mnj, belonging to code words-measurements W_i and W_j of two different SVPs with indices i and j, which require the same polling frequency, constitute a new transmission codeword W_mnij = <a_mni, a_mnj>₂, which is transmitted at a frequency f_otri^(mn). Similarly, their upper half of words W_snij = <a_sni, a_snj>₂ are combined into a new word W_snij of the same bit width, which is accepted in the modernized on-board telemetry system (BRTS), but is transmitted with a lower sampling frequency f_otri^(sn) = f_otri^(mn)/k, where k is the accepted coefficient of its division.

EFFECT: technical result is to provide noise-immune coding of slowly varying parameters (SVP) with simultaneous reduction of redundancy of transmitted data.
