This paper presents a low-complexity algorithm and architecture to compute power spectral
density (PSD) using the Welch method. The Welch algorithm provides a good estimate of the …

This paper presents an in-depth study of the implementation and characterization of fast
Fourier transform (FFT) pipelined architectures suitable for broadband digital channelized …

This brief presents the feedforward short-time Fourier transform (STFT). This new approach
is based on reusing the calculations of the STFT at consecutive time instants. This leads to …

Feature extraction has more importance in fault diagnosis and also to identify the important
changes of rotary machines. Rolling elements are an important part of a rotary machine. The …

A novel architecture for computing the fast Fourier transform on programmable devices is
presented. Main results indicate that the use of an 8× 8 parallel structure for realizing this 64 …

Differential phase measurements using two receiver channels are used to calculate the
angle of arrival of a target signal. A monobit receiver architecture is a desirable receiver type …

This paper presents a low complex and low latency architecture to compute short-time
Fourier transform (STFT). This new approach is based on reusing the calculations of the …

A primary concern in the current radar-receiver design involves the critical issue of setting a
threshold level that is optimal for all operating conditions. A novel adaptive thresholding …

The Square Kilometre Array (SKA) project will be the world's largest radio telescope array.
With its large number of antennas, the number of signals that need to be processed is …

The goal of this thesis has been to reduce the hardware cost of SDF FFTs. In order to
achieve this, two methods for simplifying rotations in FFTs are presented: Decimation and …
