Variations on Information Embedding in Multiple Access and Broadcast Channels
Information embedding (IE) is the transmission of information within a host signal subject to a distortion constraint. There are two types of embedding methods, namely irreversibl...

Stochastic Resource Allocation over Fading Multiple Access and Broadcast Channels
In this paper, we consider the optimal rate and power allocation that maximizes a general utility function of average user rates in a fading multiple-access or broadcast channel. B...
