On Correlation Values of -Phase Spreading Sequences of Markov Chains
Hiroshi Fujisaki · 2002
There has recently been intense interest in spreading sequences of Markov chains. It is experimentally found that the autocorrelation values of -phase spreading sequences of some Markov chains always take real numbers. In this paper, we theo- retically give a necessary and sufficient condition that the autocor- relation values of -phase spreading sequences of Markov chains always take real numbers. We also discuss time synchronization using these sequences.
