Deep Networks for Direction-of-Arrival Estimation in Low SNR [PDF]
IEEE Transactions on Signal Processing, 2020 In this work, we consider direction-of-arrival (DoA) estimation in the presence of extreme noise using Deep Learning (DL). In particular, we introduce a Convolutional Neural Network (CNN) that predicts angular directions using the sample covariance ...

Use the Frequency Domain to Hide in Some Audio Files [PDF]
Al-Rafidain Journal of Computer Sciences and Mathematics, 2013 In this work, anew hiding algorithm is proposed that depends on using two deferent domain (spatial and frequency) to achieve and provide security and protection for transformed data, which is represented in a text message encrypted using a key of direct ...

Digital Information Hiding Techniques [PDF]
Al-Rafidain Journal of Computer Sciences and Mathematics, 2010 Information hiding, a form of watermark, embeds data into digital media for the purpose of identification and copyright. Several constraints affect this process: the size of data to be hidden, the need for robustness of these data under conditions where ...

Beyond Max-SNR: Joint Encoding for Reconfigurable Intelligent Surfaces [PDF]
International Symposium on Information Theory, 2019 A communication link aided by a Reconfigurable Intelligent Surface (RIS) is studied, in which the transmitter can control the state of the RIS via a finite-rate control link.
