An approach is proposed to the filtering of an additive mixture ultra-wideband chaotic signals and white Gaussian noise, in order retrieve useful signal receiver. The role filter performed by a passive frequency-selective circuit, identical one involved formation oscillations chaos generator. A mathematical model modulating generator, detecting receiving sequence radio pulses noisy channel desi...

The conventional receiver for DS-CDMA communications is the RAKE receiver which is a matched filter (MF), matched to the operations of spreading, pulse shape filtering and channel filtering. The RAKE receiver assumes a sparse/pathwise channel model so that the channel matched filtering gets done pathwise, with delay adjustment and decorrelation per path and maximum-ratio combining of path contr...

The high computational cost of wide-parameter-space searches for continuous gravitational waves (CWs) significantly limits the achievable sensitivity. This challenge has motivated exploration alternative search methods, such as deep neural networks (DNNs). Previous attempts [1,2] to apply convolutional image-classification DNN architectures all-sky and directed CW showed promise short, one-day ...

Limitations caused by traditional breast cancer detection and screening techniques have encouraged researchers to investigate alternative solutions. This study examines the use of a microwave-based approach for tumor in tissue related type classification using matched-filtering. Radar-like confocal microwave imaging (CMI) method constructs foundation such approach. In particular, pulse is first...

The study area is located in Jabal-Barez Ranges, southeastern part of Kerman Copper Belt (KCB), where the porphyry copper mineralization such as Kerver occurs. This article deals with the enhancement of hydrothermal alteration minerals for exploration of porphyry Cu mineralization, and differentiates intense hydrothermal alteration zones from those with low intensity. Shortwave Infrared (SWIR) ...

(ABSTRACT) This thesis presents a part of the research work at Virginia Tech on developing a prototype automatic luggage scanner for explosive detection, and it deals with the automatic detection of elongated objects (detonators) in x-ray images using matched filtering, the Hough transform, and information fusion techniques. A sophisticated algorithm has been developed for detonator detection i...

This paper presents an implementation of a GFSK receiver based on matched filtering of a sequence of successive bits. This enables improved detection and superior BER performance but requires matched filters of considerable complexity. Exploiting redundancy, and performing phase propagation of successive single-bit stages, we propose a new receiver structure of low complexity. Simulation result...

This paper presents a new denoising method for base-band communication signals corrupted by additive noise. The novelty of this paper is the use of a special MAP filter, called composed bishrink, for communication purposes. A complete statistical analysis of this filter is reported. Some simulations are presented. The results obtained are compared with the results of matched filtering technique...
