This paper aims to maximize throughput by minimizing power as possible. Scores of optimization techniques such as FFT, IFFT and memory optimization are available for reducing power of mobile OFDM systems. An approach for achieving reduction in power of MIMO OFDM system by optimizing FFT architecture is addressed in this paper. Memory references in MIMO OFDM transceivers are costly due to their long delay and high power consumption. To implement Fast Fourier Transform (FFT) algorithms on MIMO OFDM. The proposed FFT structure is the combination of memory reference reduction evaluated using performance parameters such as BER and SNR.
