OFDM is mainly used to transmit video and audio signals efficiently with high performance and speed. FFT has various applications in, digital signal processing, and biomedical applications. There is a demand for semiconductor technology in terms of high performance, low area and power consumption. This increasing power is a significant problem in current processing communication technology. Therefore, various low-power FFT processors are designed to maximise the system life and meet consumer demand by extending the battery life at a lower cost. In this thesis, FFT processor is designed by...
