Abstract
In this paper, an extended hybrid carrier system based on extended weighted fractional Fourier transform is proposed to improve the confidentiality of wireless communication. We illustrate the principles and put forward a fast algorithm to ensure the feasibility of the scheme. By extending the existing forms of WFRFT, the proposed scheme achieves a great improvement of the parameter dimensions and constructs diversified anti-interception signals, which significantly reduces the interception probability of eavesdroppers without consuming more physical layer resources or power. The validity of the EWFRFT scheme is verified by theoretical analysis and numerical simulations, and the performance of the system is evaluated in terms of the secrecy capacity, bit error rate, and computational complexity. Simulation results and analysis show that the proposed scheme remedies the defects of the existing hybrid carrier system and safeguards the physical layer security of the system effectively at the cost of a slight increase in computational complexity.
