“…In this letter, we assume an AWGN channel, infinite XPD, and evaluate the achievable security performance of the proposed scheme. Although nonideal XPD is an important consideration for the proposed scheme, its effect is less in the Ku band and precompensation methods [17,18] can also reduce the influence. In addition, we assume the equal transmission path length between two polarization channels and there is no frequency offset for these problems are solved in [19].…”

In this paper, a spectrum efficient secure transmission scheme based on directional polarization modulation (DPM) is proposed. Specifically, the polarized signals are divided into two parts, i.e., I and Q, and a dual-polarized antenna array is designed to form beams to transmit these signals. Naturally, the constellation structure is associated with the beam gain, which can be controlled to make the constellation structure distort in undesired directions. Thus the security is enhanced for the symbol error rate performance deteriorates in undesired directions. Additionally, a kind of directional modulation technique is utilized to transform one component of the polarized signal into QPSK signal and thus improves the modulation order without extra transmitting power consummation. Finally, theoretical analysis and simulation results demonstrate that the proposed scheme can improve the transmission efficiency and provide a security transmission method for wireless communication systems.

“…The authors in [32] proposed a dual-polarized phased array (PA) based PM method to enhance PLS in millimeter-wave (mm-wave) communication systems. In order to increase the secure transmission performance of a dual-polarized satellite MIMO system, a directional PM scheme using a four-element array was put forward in [33], which can be viewed as the first amalgamation of DM and PM. Recently, a combination of DM and polarization design using crossed dipole arrays was put forward in [34].…”

Directional modulation (DM), as an emerging promising physical layer security (PLS) technique at the transmitter side with the help of an antenna array, has developed rapidly over decades. In this study, a DM technique using a polarization sensitive array (PSA) to produce the modulation with different polarization states (PSs) at different directions is investigated. PSA can be employed for more effective DM for an additional degree of freedom provided in the polarization domain. The polarization information can be exploited to transmit different data streams simultaneously at the same directions, same frequency, but with fixed different PSs in the desired directions to increase the channel capacity, and with random PSs off the desired directions to enhance PLS. The proposed method has the capability of concurrently projecting independent signals into different specified spatial directions while simultaneously distorting signal constellation in all other directions. Mathematical analysis and design examples for single-beam and multi-beam DM systems are presented. Simulation results demonstrate that the proposed method is more effective for PLS and the channel capacity is significantly improved compared with conventional antenna arrays.

“…Thus the techniques typically aims to enhance the security capacity, such as adding precoding techniques or artificial noise [1,[7][8][9]. The other approach is to deteriorate the eavesdropper's channel quality, for instance, through direction modulation [10,11] or physical layer encryption techniques [12], the constellation structure of the signal is effectively distorted, which make it difficult for the eavesdropper to demodulate any useful information. These techniques can protect the target signal, but the signal can still easily be detected, the system is vulnerable to jamming attacks [13].…”

A novel scheme based on polarization modulation and the weighted fractional Fourier transform (PM-WFRFT) is proposed in this paper to enhance the physical layer security of dual-polarized satellite systems. This scheme utilizes the amplitude and phase of the carrier as information-bearing parameters to transmit the normal signal and conceals the confidential information in the carrier's polarization state (PS). After being processed by WFRFT, the characteristics of the transmit signal (including amplitude, phase and polarization state) vary randomly and in nearly Gaussian distribution. This makes the signal very difficult for an eavesdropper to recognize or capture. The WFRFT parameter is also encrypted by a pseudo-random sequence and updated in real time, which enhances its anti-interception performance. Furthermore, to prevent the polarization-based impairment to PM-WFRFT caused by depolarization in the wireless channel, two components of the polarized signal are transmitted respectively in two symbol periods; this prevents any mutual interference between the two orthogonally polarized components. Demodulation performance in the system was also assessed, then the proposed scheme was validated with a simulated dual-polarized satellite system.
