On the rate-distortion performance of dynamic bitstream switching mechanisms
Bitstream switching is an effective way to deal with bandwidth variation in transmitting multimedia over time-varying channels. A number of bitstream switching mechanisms have bee...

On Scaling Laws of Diversity Schemes in Decentralized Estimation
This paper is concerned with decentralized estimation of a Gaussian source using multiple sensors. We consider a diversity scheme where only the sensor with the best channel sends...
