Neural machine translation (NMT) has shown promising results and rapidly gained adoption in many large-scale settings. With the NMT model being widely used in empirical productions, its long-standing weakness in handling the rare and out of vocabulary words has been amplified a lot. In order to release the model from the stress of “understanding” the rare words, copy mechanism has been proposed to...
The digital Private Mobile Radio (dPMR) is a standard for digital trunked system which is proposed by European Telecommunications Standards Institute (ETSI). The protocol describes the Physical Layer (PL), the Data Link Layer (DLL) of Air Interface (AI), and the standardized services and facilities of the mobile radio. In this paper, we propose a Digital Base-band (DBB) processing unit, including...
The cooperative CDMA system proposed in this paper performs two phases of transmission. In phase I, each user node transmits its own information which is received by the base station (BS) as well as the other user nodes; in phase II, each partner node relays a processed version of the information received in the previous phase. Two iterative detectors are developed at the B S to combat multiple access...
In this paper, Spatial Correlation-based Distributed Compressed Sensing (SCDCS) model and algorithm are presented in Wireless Sensor Networks (WSN), where spatial correlation and joint sparse models between the sensor nodes can be exploited in order to compress and reconstruct sensor observations in an energy efficient manner based on coding/decoding algorithm of SCDCS. Finally, the analysis of relationship...
This paper proposes a novel scheme for speech secure communication based on information hiding and Compressed Sensing (CS). The scheme first uses CS technology to compress the secret speech and reduce the information bit rate to be embedded, which is significantly different from state-of-art secret speech processing methods. Secret bit stream is then embedded into cover speech based on SCS (Scalar...
