Signal Reception Apparatus
First Claim
1. A signal reception apparatus comprising:
- an antenna which receives an OFDM (Orthogonal Frequency Division Multiplex) signal;
a frequency conversion unit configured to perform frequency conversion on the received OFDM signal to obtain a converted OFDM signal;
an A/D conversion unit configured to perform analog-to-digital conversion on the converted OFDM signal to obtain a first digital OFDM signal;
a setting unit configured to set a first interval of one OFDM symbol interval of the OFDM signal;
a demodulation unit configured to demodulate an OFDM symbol from a second digital OFDM signal corresponding to the first interval, the second digital OFDM signal being included in the first digital signal; and
a power control unit configured to control power supply to the frequency conversion unit and the A/D conversion unit in the first interval, and stop the power supply to at least one of the frequency conversion unit and the A/D conversion unit in a second interval other than the first interval.

Abstract
A signal reception apparatus includes an antenna which receives an OFDM signal, unit to perform frequency conversion on the received OFDM signal to obtain a converted OFDM signal, unit to perform analog-to-digital conversion on the converted OFDM signal to obtain a first digital OFDM signal, unit to set a first interval of one OFDM symbol interval of the OFDM signal, unit to demodulate an OFDM symbol from a second digital OFDM signal corresponding to the first interval, the second digital OFDM signal being included in the first digital signal, and unit to control power supply to the frequency conversion unit and the A/D conversion unit in the first interval, and stop the power supply to at least one of the frequency conversion unit and the A/D conversion unit in a second interval other than the first interval.
