Analysis of Power Spectrum Estimation Using Welch Method for Various Window Techniques
Pranay Kumar Rahi, Rajesh Mehra · 2014
In this paper, Power Spectral Estimation (PSE) scheme for variable data length using Rectangular, Blackman, Hanning, Bartlett and Hamming window with Welch Method. Welch method includes the periodogram having advantage of possible implementation using the Fast Fourier Transform (FFT). This method gives good resolution when optimal selection of data length samples is done. The PSE based on both Rectangular as well as Hamming window has been designed and simulated using MATLAB. It can be observed that the Rectangular and Hamming give better results than other windows like Bartlett, Hanning and Blackman window.
