Abstract
An Arbitrary Waveform Generator (AWG) synthesizes and generates an SSC modulated signal by generating a modulating waveform with a frequency of an SSC modulation frequency, calculating the number of samples per data bit (SPUI) as a ratio of an upsampling frequency to a data rate of a data stream, calculating an amplification factor as the ratio of SSC deviation frequency to data rate of the data stream, generating the array of SSC Edges containing the edge variation with respect to single sample per bit, multiplying the amplification factor to the modulating waveform, generating an array of SSC Edges Upsampled, containing edge variations with respect to an Upsample factor per bit, and multiplying SSC Edges with SPUI; calculating the resultant bit duration SSC Bit Duration as the sum of SSC Edges Upsampled and SPU, and calculating the successive summation of SSC Bit Duration, to get SSC Bit Position.
