Abstract:
1. A method of generating an offset sequence for use as a pseudo-random number (PN) code in a wireless communication, the method comprising acts of: generating a reference sequence; determining an initial state vector based at least in part on a mask associated with a first offset from the reference sequence, the initial state vector operating initially as a current state vector; and generating the offset sequence beginning at the initial state vector, the offset sequence offset from the reference sequence by the first offset, wherein generating the offset sequence includes generating a plurality of bits of the offset sequence on each of a plurality of iterations, each of the plurality of iterations comprising acts of: providing i bits of the current state vector as a portion of the offset sequence, i having a value greater than 1; and computing a subsequent state vector advanced at least i states from the current state vector, the subsequent state vector operating as the current state vector for a next iteration of the plurality of iterations.
