DISCREPANCY ESTIMATES FOR ROTATION SEQUENCES AND OSCILLATION SEQUENCES

Asian-European Journal of Mathematics, 2012
Two kinds of sequences, which are of interest in problems of uniform distribution and dynamical systems, are considered. The rotation sequences (or Kronecker sequences) (KS) are closely related to the orbits of the rotation map and the oscillation sequences (OS) are a discrete-time form of orbits of the simplest oscillators.

On Simultaneous System and Input Sequence Estimation

IFAC Proceedings Volumes, 1992
Equalization is concerned with estimation of the input sequence of a linear system given noisy measurements of the output signal. In case the system description is unknown we have the problem of blind equalization. A scheme for blind equalization which is based on the assumption that the input signal belongs to a finite alphabet is proposed.

Endometrium estimation in a sequence of ultrasonic images

Computerized Medical Imaging and Graphics, 2001
In this paper a novel algorithm for motion estimation of the endometrium in a sequence of ultrasonic images is presented. The algorithm used is based on the criterion that a pixel of a motion object at different times has a different gray value. The motion estimation includes motion frequency and thickness; the former one is determined by the detection

Parameter estimation of quasi-periodic sequences

ICASSP-88., International Conference on Acoustics, Speech, and Signal Processing, 2003
Measurements of a process described by t(i)=k/sub i/T+ tau + eta (i), (i=1, 2, . . .), where k/sub i/ are unknown integers and ( eta (i)) is a white noise, are considered. The estimation of the 'period' T and 'phase' tau of such processes is often required in communications and radar. Popular linear regression techniques for this estimation problem are

Delayed decision-feedback sequence estimation

IEEE Transactions on Communications, 1989
The authors delayed-decision-feedback sequence estimation (DDFSE) for uncoded PAM signals is considered. Estimates on the performance of the algorithm are given, and simulation results are provided for several examples. A more general form of DDFSE applicable to coded modulation systems is also presented. As an example, detection of trellis-coded QPSK (

Maximum-Likelihood Sequence Estimation Sequence for OFDM

1996
In this paper, Maximum-Likelihood Sequence Estimation (MLSE) for OFDM is derived together with a corresponding upper bound on probability of error. The error bound of the MLSE is used to assess the performance of an OFDM system with a two-path channel and a linear zero-forcing equaliser.

Constructing estimator-sequences

1990
The purpose of Section 2 was to justify P(К*(⋅,P)2) as the “as. variance bound” for e.s. Often e.s. attaining this bound can be found by ad hoc methods. In many cases, such e.s. are already available, and the role of the “local theory” is confined to establish their as. optimality. This is, in particular, the case if the tangent space is full, i.e. T(P,

Motion Estimation in Colour Image Sequences

2012
Greyscale methods have long been the focus of algorithms for recovering optical flow. Yet optical flow recovery from colour images can be implemented using direct methods, i.e., without using computationally costly iterations or search strategies.

Raising the estimate of functional human sequences.

Genome research, 2007
While less than 1.5% of the mammalian genome encodes proteins, it is now evident that the vast majority is transcribed, mainly into non-protein-coding RNAs. This raises the question of what fraction of the genome is functional, i.e., composed of sequences that yield functional products, are required for the expression (regulation or processing) of ...
