Low-Cost Transceiver Architectures 60 GHz Ultra Wideband WLANs
2009/9/2
Millimeter-wave multiport transceiver architectures dedicated to 60 GHz UWB short-range communications are proposed in this paper. Multi-port circuits based on 90° hybrid couplers are intensivel...
BEP/SEP and Outage Performance Analysis of L-Branch Maximal-Ratio Combiner for κ‐μ Fading
BEP/SEP Outage Performance Analysis L-Branch Maximal-Ratio Combiner
2009/9/2
Maximal-ratio combiner (MRC) performances in fading channels have been of interest for a long time, which can be seen by a number of papers concerning this topic. In this paper we treat bit error prob...
We present multiband antennas configurations for SDR applications. Using a composite folded dipole structure as starting point, we derived more complex antenna configurations to support multiple commu...
Common OFDM system contains redundancy necessary to mitigate interblock interference and allows computationally effective single-tap frequency domain equalization in receiver. Assuming the system impl...
In inter-frame coding of H.264/AVC standard, not only seven inter-partition modes but also intra-modes are taken into account for seeking the best coding mode so as to maintain higher encoding efficie...
Implementing a DVB-T/H Receiver on a Software-Defined Radio Platform
DVB-T/H Receiver Software-Defined Radio Platform
2009/9/2
Digital multimedia broadcasting is available in more and more countries with various forms. One of the most successful forms is Digital Video Broadcasting for Terrestrial (DVB-T), which has been deplo...
Compressed video sequences are vulnerable to channel errors, to the extent that minor errors and/or small losses can result in substantial degradation. Thus, protecting compressed data against channel...
The growing diffusion of new services, like mobile television and video communications, based on a variety of transmission platforms (3G, WiMax, DVB-S/T/H, DMB, DTMB, Internet, etc.), emphasizes the n...
A novel technique for implementing statistical multiplexing (StatMux) of broadcast services over Digital Video Broadcasting for Handhelds (DVB-H) channels is proposed. DVB-H uses a time-sliced transmi...
A Geometry-Inclusive Analysis for Single-Relay Systems
Geometry-Inclusive Analysis Single-Relay Systems
2009/9/2
Successful message relay, or the quality of the interuser channel, is critical to fully realize the cooperative benefits promised by the theory. This in turn points out the importance of the geometry ...

P2P MPEG FGS Encoding Multipoint Video Transmission Internet
2009/9/2
In the last years Peer-to-Peer (P2P) systems have gained ground for content sharing between communities, determining a real revolution on the Internet. The characteristics of P2P systems make them a v...
Multiple Description Coding Using Data Hiding and Regions of Interest for Broadcasting Applications
Multiple Description Coding Data Hiding Broadcasting Applications
2009/9/2
We propose an innovative scheme for multiple description coding (MDC) with regions of interest (ROI) support to be adopted in high-quality television. The scheme proposes to split the stream into two ...
