AbstractPhysical layer security techniques have received increasing interests in recent years due to their ability to provide additional security and their ability to be combined with conventional higher layer security measures. One such physical layer security technique is the directional modulation (DM), where the goal is to provide unhindered communication in an intended direction while hindering the communication in unintended directions. In this paper, we study the effect of Rician fading on a system employing a DM technique that minimizes the intersymbol distance in unintended directions. The performance of the system is investigated for varying ratios of the line-of-sight and scattered signal power, or Rician K-factors. The effect of Rician fading on the bit error rate (BER) performance in intended and unintended directions is studied.
