This study presents, design of modified R2MDC with pipelined Technique. Radix-2 Multipath Delay commutators is the one type of Radix-2 FFT. Wireless networks have found a significant place in the growing technologies. Orthogonal Frequency Division Multiplexing (OFDM) is a key technique used in wireless networks for high speed operation, high data capacity and spectral efficiency. The Fast Fourier Transform (FFT) are essential in the field of Digital Signal Processing (DSP), widely used in communication systems, especially in Orthogonal Frequency Division Multiplexing (OFDM) systems. Not a lot of research has been done on modified R2MDC FFT in OFDM. In this study, we propose a modified R2MDC 8-Point FFT in which pipelining technique is used in each Butterfly unit architecture. Using this technique through VLSI simulations it is found to reduce the delay and increase the throughput and hence is suitable for OFDM. This method can be extended to OFDM implementation that is apt for Wireless Networks.
