A signal reception apparatus is provided that includes an antenna which receives an orthogonal frequency division multiplexing (OFDM) signal, a unit to perform frequency conversion on the received OFDM signal to obtain a converted OFDM signal, a unit to perform analog-to-digital (A/D) conversion on the converted OFDM signal to obtain a first digital OFDM signal, a unit to set a first interval of one OFDM symbol interval of the OFDM signal, a 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 a 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.
