  • Patent number: 8327160
    Abstract: In a remote controller, a startup time or a first time duration until the startup time is input into an input unit. A timer unit counts a clock time or a second time duration.

  • Patent number: 7570578
    Abstract: 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.
