Fig. 7From: Hybrid digital-analog coding with bandwidth expansion for correlated Gaussian sources under Rayleigh fadingExperimental seg-SNR of speech test set 2 on channels with different mean CSNRs. Both HDA-PQ prediction order and HDA-TQ transform block size are 10. a \(\bar {\theta }=15\), left: b=3, right: b=5. b \(\bar {\theta }=25\), left: b=3, right: b=5Back to article page
