Dense Gaussian Sensor Networks: Minimum Achievable Distortion and the Order Optimality of Separation
14 years 11 months ago
We investigate the optimal performance of dense sensor networks by studying the joint source-channel coding problem. The overall goal of the sensor network is to take measurements...
