Abstract
An LFRS (,) calculates a PN sequence using Fibonacci form, such that when an offset is calculated from a known state, the bits of the new state comprise a block of sequence bits. Accordingly, to calculate a block having a length less than the length of the LFSR (,), all bits of the desired block can be calculated in a single offset calculation. If the block has a length greater than the length of the LFSR, one or more additional masks can be used to calculate the additional bits of the block sequence. Zero insertion is also supported.
