给出了正交化滤波器组中编码增益最大化的充要条件。这些条件被称为去相关条件和优势条件。虽然每个条件单独只是必要条件而不是充分条件，但我们证明了它们共同构成了一组充要条件。然后，我们展示了如何以满足这些条件的方式来设计分析滤波器响应。
We derive a set of necessary and sufficient conditions for maximizing the coding gain in an orthonormal filter bank. These are referred to as the decorrelation and majorization conditions. While each condition individually is only necessary and not sufficient, we show that together they form a set of necessary and sufficient conditions. We then show how to design the analysis filter responses in a way that satisfies these conditions.
