Multiple Input Multiple Output Orthogonal Frequency Division Multiplexing technology is an advanced transmission technique for wireless communication systems. In this paper, the 64 point pipeline FFT/IFFT processor is introduced for efficient implementation of OFDM architecture. The IFFT processor is used to modulate the subcarrier in transmitter section and FFT processor demodulate the subcarr...

A systematic approach is presented for automatically generating variable-size FFT/IFFT soft intellectual property (IP) cores for MIMO-OFDM systems. The finite-precision effect in an FFT processor is first analyzed, and then an effective word-length searching algorithm is proposed and incorporated in the proposed IP generator. From the comparison, we show that our analysis of the finite precisio...

Electric arcing is a common problem in DC power systems. To overcome this problem, the electric arc detection algorithm has been developed as faster alternative to existing algorithms. The following issues are addressed paper: calculation of proposed incremental decomposition signal over time; computational complexity Fast Fourier Transform (FFT) and decomposition; test bench used measure arcs ...

Image processing is a recent trend that is grabbing attention in almost all areas like space, medical, defence, authentication systems etc. ,. Discrete Fourier Transforms is one of the most used transforms in image processing. Discrete Fourier Transform helps to transform the signal from spatial domain to frequency domain which is often used for filtering, correlation analysis and spectrum anal...

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. I...
