The Periods of a Class of Nonlinear Feedback Shift Register Sequences. Issue 2 (1st March 2016) - Liang, Wanwan
Abstract : In this paper, we discuss a class of n ‐stage Nonlinear feedback shift registers (NFSRs). Applying the knowledge of algebra, the least periods of the sequences generated by these NFSRs with symmetric feedback functions can be characterized. This approach simplifies the problem of determining the periods of the NFSR sequences and it generalizes some Cheng's results.
