In this paper, a novel minimum noise structure is introduced for ladder-based biorthogonal filter banks. The proposed MInimum Noise LAdder-based Biorthogornal (MINLAB) coder ensures that the noise gain of the quantizers is unity, even though the system is not orthonormal. The coding gain of the optimal MINLAB coder is always greater than unity. For both the AR(1) and MA(1) processes, the MINLAB coder with 2 taps outperforms the optimal orthonormal coders of any number of taps. In addition to its superior coding performance, the optimal biorthogonal coder has a very low design and implementational cost. Moreover the proposed coder enjoys many advantages that make it an attractive choice for lossy/lossless data compression.
