Abstract
Pseudonoise (PN) sequences of maximal length (m-sequences) are widely used in a number of applications in communication systems. Very often a need arises to rapidly access any position within the sequence. Moreover, it is important to be able to predict the time required to execute the transition from one state of the sequence to any other. Presented in this paper, is a method that will give access to any one of the 2 super N-1 positions of an m-sequence within N clock pulses, N being the number of stages in the shift register used to produce the sequence. The method is easily implemented on hardware logic circuitry and requries no software operation.
