Data hiding schemes using complete complementary codes have been developed for image and audio signals. It has been shown that a high payload and a low bit-error-rate can be achieved by such data hiding strategies because of the ideal auto-and cross-correlation properties of complete complementary codes. The authors have proposed an emergency broadcasting system based on the data hiding scheme using...

Information hiding schemes using complete complementary codes (CCCs) have been developed for image data. It has been shown that a high payload and a low bit-error-rate (BER) can be achieved by such data hiding strategies because of the ideal correlation properties of CCCs. In this work, we apply a data hiding scheme based on CCCs to audio signals. Properties such as signal-to-noise ratio (SNR) and...
In this paper, a new information theoretic algorithm is proposed for signal enumeration in DS-CDMA networks. The approach is based on the predictive description length (PDL) of the observation vector. The PDL is the length of a predictive code of observations. For signal detection, the PDL criterion is computed for the candidate models and is minimized to determine the number of signals. The proposed...
