Conference Paper: An Efficient 64point Pipelined FFT Engine
[Show abstract] [Hide abstract]
ABSTRACT: The Fast Fourier Transform (FFT) is a very important algorithm in signal processing, software defined radio and the most promising modulation technique i.e. Orthogonal Frequency Division Multiplexing (OFDM). This paper describes the design and implementation of a fully pipelined 64point FFT engine in programmable logic. The FFT takes 16bit fixed point complex numbers as input and after a known pipelined latency of 20 clock cycles produces the desired output. The input data samples are fed in parallel to the FFT engine to generate outputs in parallel. The architecture is capable of performing FFT operation without changing the internal coefficients which makes it highly suitable for practical applications. The architecture requires 25% multiplication operations compared to conventional CooleyTukey approach. Hence it leads to low power and area saving.Advances in Recent Technologies in Communication and Computing (ARTCom), 2010 International Conference on; 11/2010 
Conference Paper: VLSI implementation of fast Fourier transformation for OFDMbased highspeed wireless applications
[Show abstract] [Hide abstract]
ABSTRACT: In this paper, we introduce a fixedpoint 16bit 64 point FFT processor architecture for OFDMbased wireless applications. The processor is based on the DIT (decimationintime) radix2 butterfly FFT algorithm. A canonical signed digit is used to implement constant complex multiplications with a CSA tree for lower power and cost. The simulation shows the module can reach low cost/power and high speed for OFDMbased highspeed wireless applications.SolidState and Integrated Circuits Technology, 2004.
