Abstract
Provided are a method and system for using a non-linear feedback shift register (NLFSR) for generating a pseudo-random sequence. The method may include generating, for an n-stage NLFSR that requires more than two taps to generate a maximal length pseudo-random sequence, a pseudo-random sequence using a feedback logical operation of only a first logic gate and a second logic gate. Two non-end taps suitable for providing an at least near-maximal length pseudo-random sequence are inputs for the first logic gate, an output of the first logic gate and an end tap are inputs for the second logic gate, and an output of the second logic gate is used as feedback to a first stage of the n-stage NLFSR.
