Fig. 2From: Hybrid digital-analog coding with bandwidth expansion for correlated Gaussian sources under Rayleigh fadingAMMSE of HDA-PQ (left) and HDA-TC (right) for a Gauss-Markov source with a=0.9, as a function of the analog power allocation ρ and the outage CSNR θ o . Mean CSNR of the channel is 15 dB, and the bandwidth expansion factor is b=4. HDA-PQ prediction order is 1, and HDA-TQ transform block size is 8Back to article page
