Watermark BER and Channel Capacity Analysis for QPSK-Based RF Watermarking by Constellation Dithering in AWGN Channel

Abstract

Radio frequency (RF) watermarking is the technology that embeds the hidden information in the normal communication signals without extra bandwidth, which could be used to identify authentication or transmit secret information. Constellation dithering (CD) is one of the RF watermarking schemes and usually used for quadrature phase shift keying signals. In… (More)
