In this paper, the robust transceiver design for multi-cell distributed antenna systems is investigated, which is of great importance for the future mobile communication network architecture namely cloud radio access networks (C-RAN). In order to make the algorithm suitable for the multi-cell network with a large number of remote radio heads (RRHs), a low complexity robust design is proposed based...
An algorithm is proposed based on multiple choice of video watermarking scheme, watermark information is embedded in the video file at the video encoding stage. The scheme implements three main functions, including an optional multi-algorithm, embedded in the proportion of adjustable and extract frame number can set. We development a video watermarking system under the program design, experimental...
Digital audio watermarking is considered as an efficient way to copyright protection. A robust algorithm was proposed based on chaos theory and quantization in comlex cepstrum domain. Parameter selection is a key and unmanageable problem. In the proposed method, embedded positions and parameters (including threshold value and step length) were given. And it is helpful for improving robustness and...
