  • Multiple mask arrangement for jumping in pseudo-noise sequences
    Patent number: 6647054
    Abstract: 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.

  • Zero delay mask for galois LFSR
    Patent number: 6647051
    Abstract: A method and apparatus for the creation and use of a recursive system that generates an output that depends upon a plurality of previous outputs by first processing previous outputs to obtain processed values, storing the processed values, determining new outputs depending on the processed values by providing a connection to stored processed values, the connection being operative to connect the stored processed values to a series of switches and adders that reverse process the processed values.
