Wireless source transmission with time-varying side information

Many applications in wireless networks require the transmission of an analog source over a fading channel to be reconstructed with the minimum distortion possible, i.e. multimedia signals over cellular networks or the accumulation of local measurements at a fusion center in sensor networks. In many practical scenarios, the destination receives additional correlated side information either form other transmitters in the network or through its own sensing devices. For example, signals from repeaters in digital TV broadcasting or relay signals in future mobile networks. However, similar to the channel state information at the transmitter, it is costly to provide an estimate of the available source side information to the transmitter. © 2011 IEEE.
