A security method of physical layer transmission based on uniform circular array
|
Abstract:
A security method of physical layer transmission based on uniform circular array is proposed to guarantee the information un-eavesdropped during wireless communication. This method uses harmonic components generated by the switching function of antenna, which are modulated by the spread spectrum sequence and the spatial information. Simulation results show that the performance of capture and demodulation deteriorates obviously when the azimuth and elevation deviates from the desired receiver. And it is disabled when the deviation is beyond a certain threshold.
