Abstract (in Japanese) (See Japanese page) 
(in English) In the PON system using the OFDMA technique, there is a problem that the power consumption of the IFFT circuit for generating multiple sub-carriers increases in proportion to the speed of the sampling rate and the number of subcarriers. In this paper, we proposed power-saving implementation of IFDMA modulation processing circuit that can multiplex subcarriers at low power. And we developed 12Gbps real-time IFDMA modulation circuit of ONU that was implemented in FPGA of 40nm process for IFDMA-PON, which realized elastic bandwidth allocation and low-power implementation of 0.82W.
