Abstract

There has recently been intense interest in spreading sequences of Markov chains for asynchronous SSMA (spread-spectrum multiple-access) communication systems. It is experimentally found that the auto-correlation values of M-phase spreading sequences of some Markov chains always take real numbers. In this paper, we theoretically give a necessary and sufficient condition that the auto-correlation values of M-phase spreading sequences of Markov chains always take real numbers
