“…Moreover, in [13], signals were randomized by a pseudorandom sequence and processed by WFRFT, which further distorted the constellations and enhanced the protection for the pseudorandom sequence and the WFRFT orders. In [6,14], information was conveyed by two polarized signals and signals' PSs were randomly chosen based on the designed rule. For the legitimate user, with the shared rule, two polarized signals could be completely separated from received signals based on polarization filtering.…”

In this paper, a transmission scheme based on polarization filtering and weighted fractional Fourier transform (PF-WFRFT) is proposed to enhance the transmission security in wireless communications. Indeed, the distribution of the transmit signals processed by WFRFT can be close to Gaussian, which can significantly improve the low detection probability. However, through scanning the WFRFT order with small step size, an eavesdropper can restore a regular constellation and crack the information. To overcome the problem, in the PF-WFRFT scheme, two polarized signals with mutually orthogonal polarization state are utilized to convey the information, which are processed by WFRFT separately and added up linearly before being transmitted by dual-polarized antennas. In this manner, even by scanning the WFRFT order, recovered signals are composite ones, which make the WFRFT order and the signals’ PSs difficult to crack, thus improving the security. In addition, the polarization-dependent loss (PDL) effect on the proposed scheme is discussed and a proprocessing matrix based on the channel information is constructed to eliminate this effect. Finally, numerical results are given to demonstrate the security performance of the proposed scheme in wireless communications.

“…Accordingly the communication system can be safer whereby cooperative method [21], constellation scrambling method [22] and parallel combinatory method [23]. Except the applications mentioned above, WFRFT is also an effective method in physical layer security, especially after combining with polarization modulation [24] [25], which enhances the information safty of dual-polarized satellite systems and demonstrates better performance than the same system without it [26].…”

The transform domain communication system (Hereinafter referred to as TDCS) takes on numerous advantages, inclusive of anti-jamming and low probability of detection. Yet its application is confined by the consistent spectrum in the transmitter and receiver, which is not possible in the case of a huge distance exsits between them. In this paper, a TDCS based modified weighted fractional fourier transform (WFRFT) is proposed to solve the problem resulting from spectrum mismatching for TDCS application. The amplitude and phase information are incorporated with the TDCS signals and transmit to the receiver together in the wake of a modified WFRFT. The basic function and the TDCS signals shall be accessible to the receivers in the wake of an inverse WFRFT transform, which make sure that the original information can be demodulated properly. The system's reliability while transmitting signals with different modulation methods and with spectrum mismatching is demonstrated by bit error rate (BER). In the meantime, the constellations of the signals and the BER performances at the eavesdropper demonstrate the proposed system is better secured.

A novel wideband dual-polarized antenna with load of a disk is presented in this letter. The antenna is composed of two cross magneto-electric dipole antennas vertically fixed on an aluminum plate as ground plane, which are excited by two similar Γ-shaped coaxial feeder. Furthermore, in order to further broaden the impedance bandwidth, a disc-shaped resonator is loaded on the front end of the dipole. And a metal barrel reflector is loaded around the antenna to further improve the antenna's radiation characteristics. Measured results show that the proposed antenna achieves a 10 dB with bandwidth of 1.2-2.4 GHz, and its port isolation is higher than 28 dB. Moreover, stable radiation pattern with a peak gain of 7.7-9.2 dB is obtained within that band.
