a complete procedure for the design of w-band low noise amplifier in mmic technology is presented. the design is based on a simultaneously power and noise matched technique. for implementing the method, scalable bilateral transistor model parameters should be first extracted. the model is also used for transmission line utilized in the amplifier circuit. in the presented method, input/output ma...

1 1=f-type spectral behavior has received considerable attention in the past few years because it arises from a wide range of nature phenomena. By expressing a 1=f process as a fractional integral of white noise, we show that, if < 1, the process is stationary and follows an-stable model, while if > 1, the process has stationary-stable increments. We also provide closed form expressions for the...

In this study, digital communication based on antipodal signal transmission is analyzed under skewed alpha-stable noise whose parameters are assumed to be unknown. The receiver modelled by suboptimal detectors such as soft limiter and sign correlator which determine the transmitted binary information directly from received noisy signals. Degradation effect of skewness impulsive bit error rate i...

We show that all non-negative submodular functions have high noise-stability. As a consequence, we obtain a polynomial-time learning algorithm for this class with respect to any product distribution on {−1, 1} (for any constant accuracy parameter ). Our algorithm also succeeds in the agnostic setting. Previous work on learning submodular functions required either query access or strong assumpti...

In this paper, a new simple direct method to solve nonlinear Fredholm-Volterra integral equations is presented. By using Block-pulse (BP) functions, their operational matrices and Taylor expansion a nonlinear Fredholm-Volterra integral equation converts to a nonlinear system. Some numerical examples illustrate accuracy and reliability of our solutions. Also, effect of noise shows our solutions ...

Suppression of noise and artifacts is a necessary step in biomedical data processing. Adaptive filtering is known as useful method to overcome this problem. Among various contaminants, there are some situations such as electrical activities of muscles contribute to impulsive noise. This paper deals with modeling real-life muscle noise with α-stable probability distribution and adaptive filterin...

We prove existence and uniqueness of a mild solution stochastic evolution equation driven by standard α-stable cylindrical Lévy process defined on Hilbert space for α∈(1,2).
