چکیده
The compressive sensing method is an effective way of under-sampling array signal processing, and the measurement matrix a key technology which decisive significance to improve performance processing. In this paper, processing based on improved Hadamard was proposed. This construction by compressing zero capable reducing redundant data, enhancing non-correlation between columns, improving RIP condition, method. verified simulation real data from lake, results showed that proposed in paper has obvious advantages compared with Toeplitz Circular Matrix, m-sequence-based matrix, partial under same conditions.

An Improved Automatic EEG Signal Segmentation Method based on Generalized Likelihood Ratio
It is often needed to label electroencephalogram (EEG) signals by segments of similar characteristics that are particularly meaningful to clinicians and for assessment by neurophysiologists. Within each segment, the signals are considered statistically stationary, usually with similar characteristics such as amplitude and/or frequency. In order to detect the segments boundaries of a signal, we ...
متن کاملPhased array ultrasonic imaging using an improved beamforming based total focusing method for non destructive test
One of the novel ultrasonic phased array based scanning methods for ultrasonic imaging in non-destructive test is total focusing method (TFM). This method employs maximum available information of the phased array elements and leads to an improved defect detection accuracy compared to conventional scanning methods. Despite its high detection accuracy, TFM behaves weak in distinguishing the real ...

متن کاملWindowing Effects of Short Time Fourier Transform on Wideband Array Signal Processing Using Maximum Likelihood Estimation
During the last two decades, Maximum Likelihood estimation (ML) has been used to determine Direction Of Arrival (DOA) and signals propagated by the sources, using narrowband array signals. The algorithm fails in the case of wideband signals. As an attempt by the present study to overcome the problem, the array outputs are transformed into narrowband frequency bins, using short time Fourier tran...
