In this paper, the low information-exchange and robust precoding design for distributed antenna systems is investigated, which is of great importance for the new mobile network architecture namely cloud radio access networks (C-RAN). Relying on an interesting low complexity decomposition algorithm, a distributed robust linear minimum mean-square-error (LMMSE) precoding algorithm is proposed. Exploiting...
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...
In order to improve real-time and robustness of the lane detection and get more ideal lane, in the image preprocessing, the filter is used in strengthening lane information of the binary image, reducing the noise and removing irrelevant information. The lane edge detection is by using Canny operator, then the corner detection method is used in getting the Image corners coordinates and finally using...
Most of attacks in video digital watermarking are synchronization attacks. They can be classified as temporal and spacial synchronization attacks after characteristics of video digital watermarking are analyzed. Then synchronization robustness can be divided into inter-frame robustness and intra-frame robustness according to classifications of synchronization attacks in video digital watermarking,...
