摘要：
The design of perfect-reconstruction cosine-modulated filter banks is revisited by applying new linearization techniques for the time-domain quadratic perfect reconstruction constraints. The new techniques are analyzed to explain why they can provide improved approximation accuracy hence improved performance with insignificant increase in complexity. A design example is presented for performance demonstration and comparison.
