An Achievable Rate Region for the Broadcast Channel with Feedback
A single-letter achievable rate region is proposed for the two-receiver discrete memoryless broadcast channel with noiseless or noisy feedback. The coding strategy involves block-...

Broadcasting with a battery limited energy harvesting rechargeable transmitter
—We consider the minimization of the transmission completion time with a battery limited energy harvesting transmitter in a two-user AWGN broadcast channel. The transmitter has ...

Downlink SDMA with Limited Feedback in Interference-Limited Wireless Networks
The tremendous capacity gains promised by space division multiple access (SDMA) depend critically on the accuracy of the transmit channel state information. In the broadcast chann...

Opportunistic Grassmannian Beamforming for Multiuser and Multiantenna Downlink Communications
Scheduling in a broadcast channel based on partial channel-state-information at the transmitter is carried out in an opportunistic way. In this paper, the number of generated beams...

The pre-log of Gaussian broadcast with feedback can be two
Abstract-- A generic intuition says that the pre-log, or multiplexing gain, cannot be larger than the minimum of the number of transmit and receive dimensions. This suggests that f...

The capacity region of a class of broadcast channels with a sequence of less noisy receivers
The capacity region of a broadcast channel consisting of k-receivers that lie in a less noisy sequence is an open problem, when k 3. We prove that superposition coding is indeed ...

Multi-rate Support for Network-Wide Broadcasting in MANETs
Abstract. Mobile ad-hoc networks (MANETs) utilize broadcast channels, where wireless transmissions occur from one user to many others. In a broadcast channel the same transmission ...

Coding Constructions for Blacklisting Problems without Computational Assumptions
Abstract. We consider the broadcast exclusion problem: how to transmit a message over a broadcast channel shared by N = 2n users so that all but some specified coalition of k excl...

Multiparty Quantum Coin Flipping
We investigate coin-flipping protocols for multiple parties in a quantum broadcast setting: • We propose and motivate a definition for quantum broadcast. Our model of quantum ...

Multiplexing Video on Broadcast Channels via Convex Programs
— We propose a joint power- and rate-control scheme to broadcast a multiplicity of video sequences over a broadcast channel. The formulation is intended to be general in scope, w...
