@inproceedings{Jindal2003OptimalPA, title={Optimal Power Allocation for Parallel Gaussian Broadcast Channels with Independent and Common Information}, author={N. Jindal and A. Goldsmith}, year={2003} }

We consider a set of parallel, two-user Gaussian broadcast channels, where the transmitter wishes to send independent information to each of the receivers and common information to both receivers. The ca- pacity region of this channel has been implicitly characterized in the past, but we provide an explicit characterization of the power and rate allocation schemes that achieve the boundary of the three-dimensional rate region. Unlike the broadcast channel with only independent information, we… CONTINUE READING
