Abstract:
Mathematical descriptions of the IRIG 106 randomizer and derandomizer are developed and used to show the impact of shift register initial conditions on the input/output relations for a cascade of randomizer and derandomizer operations (the normal order) and a cascade of derandomizer and randomizer operations (the reverse order). The results show that for the normal order, mismatched randomizer and derandomizer shift register initial conditions impact at most the first 15 bits. But for the reverse order, mismatched randomizer and derandomizer initial conditions impact all of the bits. Consequently, the shift register initial conditions must be the same to recover data when the randomizer and derandomizer are operated in the reverse order. The mathematical representation is based on polynomials and the generating function concept and the results are confirmed using computer programs based on bit-level operations.
