Abstract:

A method based on Logistic map to generate poly phase (2n phases) sequence proposed in this paper. It gives the sufficient condition for this map to produce an independent and identically distributed (i.i.d) poly phase pseudo r andom (PN) sequence. The theoretical and numerical analyses show that the sequen ce also has a high complexity. It gives a fast algorithm to generate this sequence and general expression of the sequence in the paper too. The sequence can be used in fields such as information security and spread spectrum communication.
