چکیده

| In this paper, we propose a combined source and channel coding system for multimedia information sources, which outputs di erent kinds of information on a frame by frame basis. We use a source encoder which has several probability tables for each medium and a channel encoder which has several convolutional codes for unequal error protection. Computer simulation shows the performance of our system.

Adaptive-Rate Image Watermarking based on Spread Spectrum Communication Technique

As the Internet becomes more and more populous, people concern more about the copyright protection issue for digital data such as images and audio. Digital watermarking technique can hide data in images or audio to indicate the data owner or recipient. Therefore, it can protect the copyright. There were a lot of papers discussing how to embed watermark into images in recent years. However, few ...

Multi-video-scheme Videoconferencing Applications

The videoconferencing applications transmit video and audio data through data networks. The current networks such as the Internet are heterogeneous: their subnets may possess di erent bandwidths. When a videoconference covers subnets of di erent bandwidths, multiple video coding schemes of di erent bandwidth requirements can be used at the same time to make good use of the bandwidth resources. ...

Time-Varying Frequency Fading Channel Tracking In OFDM-PLNC System, Using Kalman Filter

Physical-layer network coding (PLNC) has the ability to drastically improve the throughput of multi-source wireless communication systems. In this paper, we focus on the problem of channel tracking in a Decode-and-Forward (DF) OFDM PLNC system. We proposed a Kalman Filter-based algorithm for tracking the frequency/time fading channel in this system. Tracking of the channel is performed in the t...

Unsupervised Content-Based Identification of Fake News Articles with Tensor Decomposition Ensembles

Social media provide a platform for quick and seamless access to information. However, the propagation of false information, especially during the last year, raises major concerns, especially given the fact that social media are the primary source of information for a large percentage of the population. False information may manipulate people’s beliefs and have real-life consequences. Œerefore,...

State Dependent Multi channel Queuing System with Ordered Entry

In the present study, we analyze the multi-channel service system with ordered entryfrom finite-source and finite-storage at each channel. The arrival and service rates are assumedto be state dependent. The steady state probabilities of the system are obtained by usingChapmann-Kolmogorov equations. Some other performance indices viz. utilization of servers,expected number of units in the system...
