The alpha stable noise sequence which is used for random carrier, is modulated
by the binary message sequence to achieve the purpose of secure communication
in some scenarios, such as military communications. The correlation between
the first and the latter half symbol period of a stable non-Gaussian noise sequence
carries the binary information. The receiver of the proposed random communication
system demodulates the received signal by calculating the correlation coefficient
between the first and the latter half sybmol period of the transmitted noise
sequence to recover the binary message sequence. The proposed communication
system significantly simplifies the structure of the transceiver because only
one alpha-stable noise source in the transmitter and a simple non-coherent demodulation
in the receiver are required. To evaluate the proposed system, the Bit Error
Rate (BER) performance under additive white Gaussian noise channel is analyzed.
And simulation results show that the BER of the system is very low, thus proving
that system proposed is rational and secure.]]>Wu, Z. and H. Zuo,2013Dezhi, L., G. Xuemai and G. Qing,2011Shao, M. and C.L. Nikias,1993Wang, K., Z.J. Xu, Y. Wu and J.Y. Hua,2012Dimitrov, K.E., J.A.
