The Stability Region of the Two-User Degraded Gaussian Broadcast Channel
نویسندگان
چکیده
The stability region of the two-user degraded Gaussian broadcast channel is characterized in this paper. Two simple power allocation schemes are considered, namely fixed and queue-aware power control. We then provide convexity/concavity conditions for the stability region and we investigate the aggregate stable throughput of the

Submitted to the IEEE Transactions on Information Theory , July 2005 Cooperative Relay Broadcast Channels
The capacity regions are investigated for two relay broadcast channels (RBCs), where relay links are incorporated into standard two-user broadcast channels to support user cooperation. In the first channel, the Partially Cooperative Relay Broadcast Channel, only one user in the system can act as a relay and transmit to the other user through a relay link. An achievable rate region is derived ba...
متن کاملThe Capacity Region of Gaussian Broadcast Channels with Intersymbol Interference
We derive the two-user capacity region with and without common information for a Gaussian broadcast channel with intersymbol interference, assuming colored Gaussian noise and an input power constraint. The proof is achieved by rst deening a similar channel model, the circular broadcast channel, which can be decomposed into a set of parallel degraded broadcast channels. The capacity region for p...
متن کاملOptimal Power Allocation for Parallel Gaussian Broadcast Channels with Independent and Common Information
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 capacity 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...
متن کاملThe Secrecy Rate Region of the Broadcast Channel
In this paper, we consider a scenario where a source node wishes to broadcast two confidential messages for two respective receivers, while a wire-tapper also receives the transmitted signal. This model is motivated by wireless communications, where individual secure messages are broadcast over open media and can be received by any illegitimate receiver. The secrecy level is measured by equivoc...
متن کاملDuality, achievable rates, and sum-rate capacity of Gaussian MIMO broadcast channels
Abstract— We consider a multi-user multiple input multiple output (MIMO) Gaussian broadcast channel (BC), where the transmitter and receivers have multiple antennas. Since the MIMO broadcast channel is in general a non-degraded broadcast channel, its capacity region remains an unsolved problem. In this paper, we establish a duality between what is termed the “dirty paper” achievable region (the...
