Phased Dithered Watermarking for Physical Layer Authentication
Nathan West · SHAREOK (University of Oklahoma; Oklahoma State University; Central Oklahoma University) · 2014
Wireless protocols can have authentication added at the physical layer without breaking the protocol for unaware clients. This study develops closed form expressions for the probability of bit errors when a technique called phase-dithered watermarking is used to add such an authentication message. The probability of bit errors is found for both message and authentication signals using phase-dithered watermarking on BPSK, QPSK, QAM, and DBPSK. When applicable results are compared to similar studies and confirmed with computer simulations.
