This paper investigates the bene ts of link adaptation according to the propagation conditions using multi-rate vocoders and channel coders. A multi-rate source and channel coding (MRC) system trades-o the source codec bit rate against channel codec bit rate according to the prevailing channel conditions. MRC systems continuously recon gure transmission resources to optimally combat channel deg...

This paper concerns the transmission of two independent Gaussian sources over a two-user decentralized interference channel, assuming that the transmitters are unaware of the instantaneous CSIs. The availability of the channel state information at receivers (CSIR) is considered in two scenarios of perfect and imperfect CSIR. In the imperfect CSIR case, we consider a more practical assumption of...

Several scientific works have considered the possibility to build Wireless Mesh Networks (WMN) using multi-channel IEEE 802.11 architectures. At the basis of these works is the notion of “non-overlapping” channels, i.e. with a frequency separation equal or greater than 25MHz. It is now a common assumption that multiple independent transmissions over these channels can coexist without mutual int...

Confocal laser scanning microscope (CLSM) can obtain multichannel 3D images from biological tissues for analysis of tissue structures, where each channel results from a particular fluorescent label. The visualization of the multi-channel 3D confocal microscope images is required for qualitative, interactive, and even quantitative analysis of the structures of the studied tissues. Despite the av...
