Abstract-The performance of the noncoherent differential chaos-shift-keying (DCSK) communication system over a multipath fading channel with delay spread is evaluated. Analytical expressions of the bit error rates are derived under the assumption of an independent Rayleigh fading two-ray channel model. Analytical and simulated results are presented and compared. The multipath performance of the DCSK system is also compared with that of the coherent CSK system as well as conventional generic waveform communication schemes.Index Terms-Chaos communications, delay spread, differential chaos shift keying (DCSK), multipath Rayleigh fading channel.

“…The use of chaos in communication systems is appealing due to several intrinsic properties of chaotic signals, such as aperiodic and broadband. Hence, many chaos-based communication systems have been proposed and analyzed in [11][12][13][14][15][16][17][18][19][20][21][22][23], among which the chaos shift keying (CSK) scheme with coherent detection was firstly proposed in [12,14] to encode digital symbols with chaotic signals. However, the sensitive dependence of chaotic signals upon initial condition makes it very difficult to replica signal in the receiver [18], i.e., non-coherent detection of received signal has advantage over coherent detection.…”

This paper investigates and proposes one advantageous function of a power packet dispatching system, which has been proposed by authors' group with being apart from the conventional power distribution system. Here is focused on the feature on safety of power packet dispatching which covers two aspects: information safety (protect the information of packet from attackers) and power safety (keep loads safe regarding supplied power from packet). For the purpose of achieving the information safety and the power safety, we introduce simple modulations of power packets before sending them. In particular, in order to protect the information of packets, partial packet modulation is proposed first, i.e., modulating partial information tags of packets. Modulation scheme based on chaotic signal is one possibility for this purpose and we adopt the differential chaos shift keying (DCSK) scheme in this paper. Next, the power safety can be achieved by applying pulse width modulation (PWM) to the payload of packets. Meanwhile, considering the effect of the noise on the packet dispatching, further modulation of the payload using the DCSK scheme is proposed, which can spread the spectrum of the noise. Consequently, we introduce the concept of whole packet modulation, in which PWM is applied to the payload of packets first, and then modulation using the DCSK scheme is applied throughout the whole packet. In this manner, both the information safety and the power safety can be achieved and the spectrum of noise is spread as well. Additionally, it is worth mentioning that the rigorous examination of the modulation method is not the target in this moment.

“…In chaos shift keying the binary information bits are transmitted using a pair of chaotic signals (h 1 and h 2 ) of different bit energies [16]. These binary chaotic signals are generated using the chaotic sequence generator (h(n), as shown in figure 5) using different initial conditions.…”

In the recent years, a lot of research has been done in the field of covert chaotic communication involving many known chaotic maps and the results have been very promising. In this paper the generation of binary sequence using modified chaotic sine map is discussed. The auto correlation and the cross correlation properties of the generated sequence is observed. Also, the BER of chaotic shift keying system is analyzed to check the feasibility of the generated sequence in communication purpose. The possibilities of using the generated binary sequences in radar pulse compression techniques is also explored and Peak Side lobe Ratio (PSLR) obtained is compared with other existing binary sequences.
