Maneuvering targets are di cult to track for the Kalman lter since the target model of tracking lter might not t the real target trajectory and the statistical characteristics of the target maneuver are unknown in advance. In order to track such a heavy maneuvering target, the estimation of the target turndirection is necessary. The two-stage estimator using advanced circular prediction which c...

This tutorial reviews the theory, structure and design methods for M-channel perfect-reconstruction (PR) lter banks. Some of the lter banks being considered here are the two-channel orthogonal lter bank; biorthogonal linear-phase lter banks; M-channel cosine-modulated lter banks and M-channel linear-phase lter banks. The connection with wavelet transform will be elaborated on the case of discre...

It was already known that the category of T 0 topological spaces is not itself cartesian closed, but can be embedded into the cartesian closed categories FIL of lter spaces and EQU of equilogical spaces where the latter embeds into the cartesian closed category ASSM of assemblies over algebraic lattices. Here, we rst clarify the notion of lter space|there are at least three versions FIL a FIL b...

This article considers lter banks for sub-band coding of discrete time electrocardiogram (ECG) signals. Two parallel FIR lter banks are optimized and compared with a classic tree-structured lter bank. The new lter banks give a decrease in signal distortion from 0.6 to 0.8 % PRD compared to the reference lter bank.

Unitary and nonunitary lter banks with uniform frequency separation have been extensively studied in the past. Improvement in coding gain has been achieved when allowing for nonunitary lter banks in image coders. Subjective improvements can be achieved by employing nonuniform lter banks. The paper presents a method to construct nonuniform nonunitary perfect reconstruction lter banks. A polyphas...

Roger L. Claypoole, Jr. and Richard G. Baraniuk, Rice University Summary We introduce and discuss biorthogonal wavelet transforms using the lifting construction. The lifting construction exploits a spatial{domain, prediction{error interpretation of the wavelet transform and provides a powerful framework for designing customized transforms. We discuss the application of lifting to adaptive and n...

This paper is about the eigenvalues and eigenvectors of (# 2)H. The ordinary FIR lter H is convolution with a vector h = (h(0); : : : ; h(N)), the impulse response. The operator (# 2) downsamples the output y = h x, keeping the even-numbered components y(2n). Where H is represented by a constant-diagonal matrix | this is a Toeplitz matrix with h(k) on its kth diagonal | the odd-numbered rows ar...
