... sequences are somehow degraded while using R scheme, such as “Foreman” and “Highway” (the possible reason has been explained in Section 4.2). As the hybrid scheme between E-BMA and R, H scheme presents its ... would affect the performance of these two schemes due to the distribution of smooth regions and nonsmooth regions. For example, R scheme achieves the higher prediction accuracy...

Letting U h (p)Λ h (p)U H h (p) be the eigendecomposition of the matrix D H h (p)D h (p), the vector y h (p) can be whitened through the following pro- cessing y h, w (p) ... = Λ −1/2 h (p)U H h (p)y h (p). Now, since the vector y h, w (p) is the superposition of the useful term Λ −1/2 h (p)U H h (p)b h (p) and of additive white thermal n...
