| Abstract(in English) | In recent years, the concept of IoT has attracted attention. It utilize the data obtained by connecting the things to the Internet. The current item in conformity with IoT uses wireless communication to transceiver the data between censer and node. IEEE802.11ah as new wireless communication for IoT is developed by IEEE working group now. But it has become necessary to save power of communication circuit to establish IEEE802.11ah. On the other hand, OFDM technique has been used in way communication. FFT and IFFT are essential for high-speed calculation of OFDM system. So the proportion of arithmetic circuit area and power consumption of FFT and IFFT circuit is very large in the entire system. From the above, object of this study is intend to design and develop a low-power FFT/IFFT circuit for IoT. In this presentation, we report the results of experiment of bit error rate and packet error rate of each bit word by decode simulator switched various digital modulation and progress of the pipelined FFT circuit design. |
