Notes/Equations
  1. This model is used to generate the bit pattern specified by DataPattern:
    • random: generate the random bit stream
    • PN9: PN code using generating polynomial x9+ x4+ 1, seeded by 1234567
    • PN15: PN code using generating polynomial x15+ x + 1, seeded by 1234567
    • bits_repeat: convert the integer specified by RepBitValue as bit stream
    • user_file: generate the data stream specified by UserFileName
  2. The default data pattern period is:
    • random: 1
    • PN9: 511
    • PN15: 32767
    • bits_repeat: 8
    • user_file: length of the file
  • No labels
