Chaotic-based Orthogonal Frequency Division Multiplexing with Index Modulation

Orthogonal frequency division multiplexing with index modulation (OFDM-IM), stands out among conventional communication technologies, as it uses the indices of available transmit entities. Thanks to such an approach, offers a novel method for transmission extra data bits. Recent years have seen great interest in chaos-based communications. The spectrum-spreading signals used chaotic signal technologies are orthogonal existing mixed signals. This paper presents how well non-coherent differential chaos shift keying system performs across AWGN. Different types detection methods simulated, bit error rate and power spectral density calculated then compared standard OFDM modulation. results simulations concerning performance DCSK system, adding security proposed solution offering comparable performance, presented well.
