Information-Spectrum Characterization of Broadcast Channel with General Source

About priority encoding transmission

Recently, Albanese et al. introduced priority encoding transmission (PET) for sending hierarchically organized messages over lossy packet-based computer networks [1]. In a PET system, each symbol in the message is assigned a priority which determines the minimal number of codeword symbols that is required to recover that symbol. This note revisits the PET approach using tools from network infor...

Distortion Bounds for Source Broadcast Problem

This paper investigates the joint source-channel coding problem of sending a memoryless source over a memoryless broadcast channel. An inner bound and several outer bounds on the achievable distortion region are derived, which respectively generalize and unify several existing bounds. As a consequence, we also obtain an inner bound and an outer bound for degraded broadcast channel case. When sp...

Joint Source and Relay Beamformer Design for General MIMO Relaying Broadcast Channel with Imperfect Channel State Information

Optimal 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...

Hybrid Digital-Analog strategies for Source-Channel Broadcast

We consider the problem of transmission of information sources with memory over a broadcast channel. This is motivated by the practical application of the design of audiovisual broadcast systems for digital TV/digital radio. Using a parallel Gaussian source model and an additive white Gaussian noise broadcast channel model, we consider the problem of information source transmission with the goa...
