TLDR
The optimal power allocation for Gaussian two users broadcast channel is derived from two optimization schemes that maximizes the sum rate capacity and the optimality of the derived schemes is verified.Abstract:
We derive the optimal power allocation for Gaussian two users broadcast channel. To find the optimal power allocation between the two users, two optimization schemes are considered. In each optimization scheme, an analytical expression for the optimal power allocation between the two users is derived. The first optimization criterion finds the optimal power allocation between the two users such that they have equal rates. Then, the optimal power allocation that maximizes the sum rate capacity is studied. In addition, numerical examples are provided to verify the optimality of the derived schemes. Keywords: Gaussian Broadcast Channel, Capacity Region, Optimization.read more

TL;DR: It is shown that capacity can be achieved by optimal power allocation over the channels, and an explicit characterization of the optimal power allocations and the resulting capacity region is obtained.

Optimal relay location and power allocation for low SNR broadcast relay channels
TL;DR: This work considers the broadcast relay channel (BRC), where a single source transmits to multiple destinations with the help of a relay, in the limit of a large bandwidth, and proposes an easy and efficient algorithm to compute all hyperarc sets, and proves they are polynomially bounded.
