FPGA Based Low Power OFDM Transceiver For 60GHz millimeter Wave Wireless Communication Systems

Next generation wireless communication systems such as IEEE 802.11ad millimeterWave(mmWave) WLAN and IEEE 802.15.3c mmWave WPAN devices operate in unlicenced 60GHz mmWave band. They offer multi giga bits per second (Gbps) data rate in the unlicenced band. Due to relatively high frequency of operation, the mmWave wireless networks operating in 60GHz should satisfy the power level limitations imposed by the regulatory bodies. The objective of this paper is to design and implement an FPGA based low power digital modulator for 60GHz mmWave wireless networks. In the first part of the paper we have designed an OFDM transceiver using Xilinx ISE. Later the power reduction techniques is achieved by the clock gating method. Finally a low power OFDM transceiver working in 60GHz is designed and implemented in kintex Xc7k70t-fbg676 using Xilinx ISE. The results show a significant power reduction as compared to the existing methods.
