Sampling-Reconstruction Procedure with a Limited Number of Samples of Stochastic Processes at Random Times

چکیده

The review of author’s publications is presented. All papers are based on the same methodological approach: the statistical description of the Sampling Reconstruction Procedure (SRP) is given on the basis of the classical conditional mean rule which provides the minimum reconstruction error. There are two cases of non uniform sampling: the sample location is arbitrary and known and the location of samples is unknown and is described by probability density function (pdf). There are some principal distinctions between reviewed papers and known publications: the number of samples is limited and arbitrary, the pdf of sampled processes is taken into account, the sampled process can be stationary and non stationary, the samples with jitter are described by some new models: the jitter pdf is the Beta distribution, any samples can have their own jitter, other can have not jitter, the jitter effect can have stationary and non stationary character. New aspects of the SRP of Markovian processes with jumps are discussed also. Key-Words: Random sampling, Optimal reconstruction, Stochastic processes.

General Problems of the Sampling-Reconstruction Procedure of Random Process Realizations

Absract: The Sampling-Reconstruction Procedure (SRP) of random process and field realizations is a very popular problem during a lot of decades. Unfortunately, this problem is completely not solved until present time. There is a well-known Balakrishnan ́s theorem. This theorem describes SRP of stationary random process realizations. This theorem is characterized by some principal drawbacks: the ...

Block-Based Compressive Sensing Using Soft Thresholding of Adaptive Transform Coefficients

Compressive sampling (CS) is a new technique for simultaneous sampling and compression of signals in which the sampling rate can be very small under certain conditions. Due to the limited number of samples, image reconstruction based on CS samples is a challenging task. Most of the existing CS image reconstruction methods have a high computational complexity as they are applied on the entire im...

@bullet Muhammad Karvllil Habib. Sampling Representations and Approximations for Certain Functions and Stochastic Processes. (under the Direction of Stamatis Cambanis.)

Sampling representations and approximations of deterministic and random signals are important in communication and information theory. Finite sampling approximations are derived for certain functions and processes which are not bandlimited, as well as bounds on the approximation errors. Also derived are sampling representations for bounded linear operators acting on certain classes of band-limi...

Sampling and Reconstruction of Wave-Number-Limited Functions in N-Dimensional Euclidean Spaces

The well-known Whittaker-Kotel 'nikov-Shannon sampling theorem for frequency-bandlimited functions of time is extended to functions of multidimensional arguments. It is shown that a function whose spectrum is restricted to a finite region of wave-number space may be reconstructed from its sampIes taken over a periodic lattice having suitably small repetition vectors. The most efficient lattice ...
