In this paper, we propose an area-efficient short-time Fourier transform (STFT) processor that can perform time–frequency analysis of non-stationary signals in real time, which is essential for voice or radar-signal processing systems. STFT processors consist a windowing module and fast processor. The length the window function related to resolution, required varies depending on application. addition, needs overlap input data samples minimize loss boundary, ratios 25%, 50%, 75% are generally...
The estimation of signal parameters via rotational invariance techniques (ESPRIT) is an algorithm that uses the shift-invariant properties array antenna to estimate direction-of-arrival (DOA) signals received in antenna. Since ESPRIT requires high-complexity operations such as covariance matrix and eigenvalue decomposition, a hardware processor must be implemented DOA estimated real time. Additionally, should support scalable number configuration for various applications because performance...
