摘要： An OFDM demodulator that demodulates an OFDM signal includes an antenna that receives a signal including delayed signals, an estimation circuit that estimates the channel response of the received signal, and a control circuit that controls a length of a retention time interval based on the estimated channel response. The retention time interval includes a time period from the head of a delayed signal having a maximum delay time in the delayed signals to the tail of a preceding signal in the delayed signals based on the estimated channel response. The OFDM demodulator also includes a retention memory that retains a portion of the received signal corresponding to the retention time period, and a selection circuit that selects an OFDM symbol based on a calculation of a maximum likelihood that the retained received signal is equivalent to a signal replica based on the channel response.

摘要： Perfluorotripentylamine, perfluoropolyether or another such high-boiling liquid is added as a foaming agent to a thermoplastic fluororesin such as a tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer resin or a tetrafluoroethylene-hexafluoropropylene copolymer resin. Because the vapor pressure of said foaming agent in the molten fluororesin is lower than that of Freon or another such low-boiling foaming agent, the cells in the foam can be made fine and uniform in diameter.
