Receiver, reception method, program and reception system

1. A receiver comprising:

a determination block adapted to determine, as a gain used to adjust the power of a received signal received with a fixed bandwidth, a gain different from that used when other band is not contained in a band of the received signal if the band of the received signal contains a desired signal band and the other band, wherein the determination block determines the gain used to adjust the power of the received signal based on a ratio of a bandwidth of the desired signal to the fixed bandwidth of the received signal; and

an acquisition block operable to acquire the bandwidth of the desired signal based on transmission control information transmitted together with the desired signal, wherein the determination block determines the gain using the bandwidth of the desired signal acquired by the acquisition block.

2. The receiver of claim 1 ,

wherein the fixed bandwidth of the received signal includes a bandwidth used to transmit the transmission control information.

3. The receiver of claim 1 , further comprising:

a reception section adapted to receive the received signal with the fixed bandwidth in a predetermined frequency band,

wherein the determination block determines the gain used to adjust the power of the received signal received by the reception section.

4. The receiver of claim 1 , further comprising:

a power adjustment block adapted to adjust the power of the received signal based on the gain determined by the determination block.

5. The receiver of claim 4 , further comprising:

a processing block adapted to suppress signals in the other band,

wherein the power adjustment block adjusts the power of the received signal in which the signals in the other band has been suppressed.

6. The receiver of claim 1 ,

wherein the received signal is a DVB-C2 modulated signal.

7. A reception method comprising:

determining, as a gain used to adjust the power of a received signal received with a fixed bandwidth, a gain different from that used when other band is not contained in a band of the received signal if the band of the received signal contains a desired signal band and the other band;

suppressing signals in the other band; and

adjusting the power of the received signal in which the signals in the other band have been suppressed.

8. A non-transitory computer-readable storage medium having stored thereon, a computer program having at least one code section executable by a computer for causing the computer to perform steps comprising:

determining, as a gain used to adjust the power of a received signal received with a fixed bandwidth, a gain different from that used when other band is not contained in a band of the received signal if the band of the received signal contains a desired signal band and the other band;

suppressing signals in the other band; and

adjusting the power of the received signal in which the signals in the other band have been suppressed.

9. A reception system comprising:

a reception section adapted to receive a signal with a fixed bandwidth in a predetermined frequency band, wherein the received signal is transmitted via a channel;

a demodulation section adapted to demodulate the received signal received by the reception section;

a signal processing section adapted to perform signal processing of the data demodulated by the demodulation section to obtain data to be transmitted;

an output section adapted to output the data to be transmitted obtained by the signal processing section,

wherein the demodulation section comprises a determination block adapted to determine, as a gain used to adjust the power of the received signal received by the reception section, a gain different from that used when other band is not contained in a band of the received signal if the band of the received signal contains a desired signal band and the other band; and

an acquisition block adapted to acquire a bandwidth of a desired signal based on transmission control information transmitted together with the desired signal, wherein the fixed bandwidth of the received signal comprises a bandwidth used to transmit the transmission control information.
