Abstract
In modern communication system widely uses MIMO-OFDM based wireless channels. The hardware based encryption and decryption techniques is implemented in Wireless channel to increase the security. The processor has complex units to perform the operation that increases the hardware complexity and power utilization. The Fast Fourier Transform used in MIMO-OFDM channel for signal processing involves complex design and requires more hardware utilization. This increases the processor complexity and also increases latency. The proposed pipelined based FFT/IFFT architecture is stimulated in Xilinx Virtex 7 FPGA and consumes 87.8298% less power and utilizes less area compare to existing technique.
