Abstract :
The Fast Fourier Transform processing is one of the key procedure in popular Orthogonal frequency Division Multiplexing (OFDM). FFT processor is the most computationally intensive component in OFDM systems[1]. The power efficiency of this component can have great impact on overall OFDM systems. The low power consumption, high speed and reduced chip area are the main concerns in VLSI implementation. In view of that this paper explores various pipeline FFT Processor architectures that aim to reduce the power consumption of these devices.
