Achievable distortion regions of Gaussian broadcast systems

We consider the problem of broadcasting a bandlimited white Gaussian source on an additive bandlimited white Gaussian noise channel with two receivers. Several hybrid digital-analog joint source-channel codes are proposed. The design principle is based on bandwidth/power splitting and matched tandem...

Description
Summary:We consider the problem of broadcasting a bandlimited white Gaussian source on an additive bandlimited white Gaussian noise channel with two receivers. Several hybrid digital-analog joint source-channel codes are proposed. The design principle is based on bandwidth/power splitting and matched tandem coding. The distortion regions of these codes are presented.
