In future deep space communication missions, VLBI(Very Long Baseline Interferometry) based on antenna array technology remains a critical detection method, which urgently requires the improvement of synthesis performance for signals. Considering this, focusing optimizing traditional grouping method applied in phase estimation algorithm, this letter proposes "L/2 to L/2" maximum correlation sign...

The results of a series of off-line signal processing experiments are presented for the experimental Large Aperture Seismic Array (LASA) located in eastern Montana. In particular, the signal-to-noise ratio gains achievable by maximum-likelihood processing, as well as other simpler forms of processing, are given as a function of frequency, aperture, and number of sensors. A partial discussion of...

Beam forming is a signal processing technique used in antenna arrays for directional signal transmission or reception. Phased array radar is very important in modern radar development, and multiple digital beams forming technology is the most significant technology in phased array radar. Digital multiple beam forming on each antenna element about large phased array radar is impossible in proces...

Bio-sensor arrays for multi-channel recording have been developed recently and signal processing platforms for those signals have been studied actively. But it's thereal situation which these technologies are generally developed and studied respectively. So the interface design between recording array and signal processing platform is also an important issue to make bio-sensor signal processing...

In this paper, we evaluate a performance of in-car speech enhancement techniques with single channel signal processing and microphone array signal processing. We employ SS (Fourier Spectral Subtraction) and WSS (Wavelet Spectral Subtraction) as single channel signal processing and delay-and-sum beamformer, eigen beamformer, AMNOR (Adaptive Microphone array for NOise Reduction), S-AMNOR, Svc-AMN...

Different signal processing and image reconstruction techniques are applied in ultrasonic non-destructive material evaluation. In recent years, rapid development in the fields of microelectronics and computer engineering lead to wide application of phased array systems. A new phased array technique, called “Sampling Phased Array” has been developed in Fraunhofer Institute for non-destructive te...

introduction automatic human emotion recognition is one of the most interesting topics in the field of affective computing. however, development of a reliable approach with a reasonable recognition rate is a challenging task. the main objective of the present study was to propose a robust method for discrimination of emotional responses thorough examination of heart rate variability (hrv). in t...

Image and video processing applications involve large multidimensional signals which have to be stored in memory modules. In application-specific architectures for real-time multidimensional signal processing, a significant cost in terms of chip area and power consumption is due to these background memory units. The multidimensional signals are usually modeled in behavioral descriptions with ar...
