Abstract
A method to receive telemetry messages over an RF channel, the method implemented by a system on a chip, in which a signal is received from the output of an input RF module, the received signal is offset in time and frequency wherein the signal, at first, is offset in time so that the offset magnitudes uniformly fill the length of one data bit, then, the signal is offset in frequency so that the offset magnitudes uniformly fill the space between the Fourier transform subcarriers, with the frequency offsets being independent of the time offsets; each signal processed at the preceding step is subjected to sequential Fourier transforms, with the first time element of each next transform immediately following the last element of the preceding transform; all messages are demodulated independently. The technical result consists in that messages can be received over multiple channels at multiple rates.
