Multiple mask arrangement for jumping in pseudo-noise sequences

摘要

Multiple masks are applied in a selected combination to a pseudo-noise sequence (PNS) output from a linear feedback shift register to shift the position of the PNS by a desired amount. Each mask shifts the PNS by a power of 2 and the selected combination of masks adds these shifts to provide the selected shift. The desired bit length of the shift in binary form is directly mapped to a combination of masks to apply the correct masking to the PNS.
