An OFDM-based Chaotic Chip Position Keying with Permutation Index Modulation

Chaotic communication is evolved from chaotic dynamic systems. Because of its the irregularity, aperiodicity, irrelevance, wide bandwidth and the inability to predict for a long time due to sensitivity to initial values [1] , chaotic signal has become a suitable carrier choice, and chaotic communication is widely studied in the fields of spread spectrum communication, multi-user communication and secure communication, etc.
