  • Patent number: 10191142
    Abstract: A method for determining a frequency modulation includes generating a symbol stream that is filtered, with multiple samples per period. Sample values represent samples of the filtered symbols at instants separated by intervals of a fraction of a time period between successive symbols. Samples of I and Q waveforms are calculated from frequency modulating a signal with the sequence of symbols. For each possible set of symbol values on which a waveform depends, an average waveform is produced over all symbol values outside the group; and on which the waveform is not to depend, all waveforms are superimposed within +/?half a period of the center symbol of each group having the same set of values and averaging the superimposed I, Q samples to produce for each group an averaged set of samples and an average waveform. Final I, Q values are stored for subsequent frequency modulation.
