Table 2 RSNR (in dB) of KLT-based transform code designs for quantizing 16-dimensional vectors (M₁ = M₂ = 16) of source model B (α = 0.32, θ = 0.9) at R₁ = R₂ = R bits/sample

From: Distributed transform coding via source-splitting

R	IKLT		SP-DKLT
(bits/sample)	EC-SQ	EC-TCQ	CEC-SQ	CEC-TCQ
0.5	10.3	11.7	12.4	14.0	(Analytical)
	10.3	11.0	11.6	12.7	(design)
1	16.6	18.0	19.1	20.6
	16.4	17.3	18.6	19.6
1.5	21.6	23.0	23.8	25.6

2	25.7	27.1	28.2	29.8
	25.2	26.6	27.8	28.6

Analytical values refer to SNR of the quantization model assumed for determining the optimal transforms and the bit-allocation
