Abstract

This paper describes conception of the correspondent authorization in the GSM link. Watermarking technology gives support for additional data hiding in the host signal. This additional data is known as a watermark signal. Watermark should be robust for loose compression in GSM 6.10 standard codec and should be transparent for human auditory system (HAS) in the host signal background. OFDM technology together with psychoacoustic MPEG model can be used for dedicated GSM authorization system. Several modes of watermark signal processing in the GSM link were presented. Results of the decoding as well as results of the ITU-R BS1116-1 subjective quality estimation tests were illustrated and commented
