Abstract:

Spectral analysis is an important area in signal processing with wide range of application. A low complexity algorithm to compute the power spectral density (PSD) using the Welch method is presented in this paper. The Welch algorithm computes spectral power at the cost of high computational complexity. In order to reduce the complexity and hardware utilization pipelining FFT approach is used. Instead of calculating an N-point FFT directly, an N/2-point FFT is calculated and two N/2-point FFTs are merged to obtain an N-point FFT.
