In this paper, an area-efficient low power Fast Fourier Transform (FFT) processor is proposed for Multi Input Multi Output—Orthogonal Frequency Division Multiplexing (MIMO-OFDM) that consists of a modified architecture of radix-2 algorithm which is described as Radix-2 multipath delay commutation (R2MDC). Orthogonal frequencydivision multiplexing is a popular method for high-data-rate wireless transmission. | Design of pipeline R2MDC FFT for implementation of MIMO OFDM transceivers using FPGA
