A method based on audio watermarking techniques for authentication and monitoring broadcasting quality of existing analog amplitude modulation (AM) shortwave radio is presented. The content and number of extracted messages can be useful to authenticate the received radio, trace the transmitting route, and represent the quality of broadcast transmitting environment, thus can be used to improve the quality of broadcast. In this paper, a robust self-synchronizing audio watermark algorithm for shortwave narrow band channel is proposed. Experimental results show that the method is robust against shortwave channel's noises and is effective to authenticate and monitor audio quality in realtime shortwave channel.
