Fig. 6From: Hybrid digital-analog coding with bandwidth expansion for correlated Gaussian sources under Rayleigh fadingA comparison of analytical and experimental AMMSEs of HDA systems designed for unit-variance speech signals, HDA-PQ (left) and HDA-TC (right). ρ and θ o values for HDA-PQ and HDA-TC systems shown here are listed in Table 4. Both HDA-PQ prediction order and HDA-TQ transform block size are 10Back to article page
