Hybrid digital-analog coding with bandwidth expansion for correlated Gaussian sources under Rayleigh fading

Abstract Consider communicating a correlated Gaussian source over a Rayleigh fading channel with no knowledge of the channel signal-to-noise ratio (CSNR) at the transmitter. In this case, a digital system cannot be optimal for a range of CSNRs. Analog transmission however is optimal at all CSNRs, if...
