Novel wireless communication technique that uses joint-space polarization architecture and channel coding to improve the efficiency and security of wireless communication

Technology Summary

Wireless communications have permeated almost every sector of life. As wireless communication expands, the demands placed upon the reliability and efficiency of wireless technology increase. Polarization is a fundamental property of an electromagnetic wave, describing its orientation as it propagates out from its source. Compared to other fundamental wave properties - frequency, amplitude, phase - polarization has been under-utilized in the context of digital communications.

Researchers at University of Notre Dame have recently developed polarization-modulated wireless communication techniques, that are particularly suited to frequency-selective environments. The technology addresses multi-carrier implementation issues by using blind carrier frequency estimation and peak-to-average ratio (PAPR) reduction approach, improving the efficiency of transmission power. Through the use of polarization, static and dynamic images can be encoded in analog polarization parameters and be transmitted without preamble requirements. Simulated polarization transmission of a QR code has also shown a potential of Low-Probability-of-Intercept (LPI) mode that greatly improves security of data transmission.
