Abstract— In this paper the higher-order statistics (HOS) specified in terms of partial triple correlation function (TCF) of Gold code is studied. Detection of Gold code is presented using fixed and adaptive threshold techniques and a triple correlation Gold code channelized receiver is proposed. The receiver takes advantage of the TCF and use it for selfsynchronization. The effect of changing ...

This paper addresses the problem of pattern noise encountered in single-stage delta-sigma modulators in the presence of a DC input signal. By utilizing state-space matrices, we explain the cause of these undesired cyclic patterns and show how a modulator’s susceptibility to tonal behavior can be determined by inspection of the system matrix A. By example of two frequently used single-stage arch...

Single-pattern real-valued spectral associative memories (SAMs) are proposed for coding and recalling sampled analog or multi-valued data patterns over noisy channels. SAMs are frequencydomain formulations of associative memory that combine the extrinsic redundancy of neural networks with the in-phase and quadrature modulation schemes of telecommunications. Data patterns, or “codewords”, are en...

– Four different dynamic circuit techniques are proposed in this paper for lowering the active mode power consumption, increasing the speed, enhancing the noise immunity, and reducing the subthreshold leakage energy of domino logic circuits. A variable threshold voltage keeper circuit technique is proposed for simultaneous power reduction and speed enhancement of domino logic circuits. The thre...

R.ADITHYA ABSTRACT In this paper an ultra low power and probabilistic based noise tolerant latch is proposed based on Markov Random Field (MRF) theory. The absorption laws and H tree logic combination techniques are used to reduce the circuit complexity of MRF noise tolerant latch. The cross coupled latching mechanism is used at the output of the MRF latch inorder to preserve the noise tolerant...

The accurate localization of S1 and S2 is essential for heart sound segmentation classification. However, current direct algorithms have poor noise immunity low accuracy. Therefore, this paper proposes a new optimal algorithm based on K-means clustering Haar wavelet transform. includes three parts. Firstly, method uses the Viola integral Shannon’s energy-based to extract function envelope energ...

exposure to high dosages of sulfur mustard (sm) can cause bone marrow depression, immune system suppression, impairment of the immune functions, and eventually results in diseases due to secondary immune disorders. in this article, we have studied the effects of this poison on iranian veterans by analysis of related published studies. in a systematic search, the effects of sm gas on iranian vic...

objective: hypericum perforatum (st. john's wort) has long been used in traditional medicine to treat a variety of internal and external ailments. the present study was done to evaluate the immumodulatory potentials of the hydroalcoholic extract of h. perforatum. materials and methods: twenty male balb/c-mice were randomly allocated in two equal groups and immunized with sheep red blood ce...

Abstract To improve the parameter estimation performance of damped real-value sinusoid in noise, a novel algorithm with high accuracy and computational efficiency is proposed that combines characteristics good anti-interference, small computation frequency-domain methods, time-domain methods. First, Discrete Fourier Transform (DFT) two-point spectrum interpolation methods are used to noise immu...

According to the characteristics of micro parts microscopic detection image, including image texture is similar, edge information too little and gray distribution Range limited, based on basic principles algorithm, analyzes traditional sharpness evaluation function. Aiming at defect that function cannot have both high sensitivity noise immunity, an algorithm local variance entropy proposed. The...
