We carried out a comparative analysis of the algorithms for detecting a rectangular impulse against Gaussian white noise under either authorized or unauthorized access to the transmitted data. We presupposed that for data transmission the binary communication system is used and that the useful information in the data is whether the signal is present or absent. The case is that unauthorized acce...

Time-frequency analysis in waveform engineering can be applied to many detection and imaging systems, such as radar, sonar, ultrasound improve their Signal-to-Noise Ratio (SNR). Recently, photoacoustic systems have attracted researchers’ attention. However, the SNR optimization problem for has not been fully addressed. In this paper, one-dimensional of response an input with finite duration ene...

A new two-step fuzzy filter that adopts a fuzzy logic approach for the enhancement of images corrupted with impulse noise is presented in this paper. The filtering method (entitled as Fuzzy Random Impulse Noise Reduction method (FRINR)) consists of a fuzzy detection mechanism and a fuzzy filtering method to remove (random-valued) impulse noise from corrupted images. Based on the criteria of pea...
