However, attention should be paid to the application of the filter, because incorrect application of the filter to the desired signal to be received can lead to suppression of even the signal to be received and lead to degradation of performance

Embodiment Construction

[0035] [Example structure of receiving apparatus]

[0036] figure 1 An example structure of an embodiment of a receiving apparatus to which the present technology is applied is shown.

[0037] figure 1 The reception apparatus 1 in is an OFDM reception apparatus configured to receive a broadcast wave of an OFDM signal transmitted from a transmission apparatus at a broadcast station not shown.

[0038] The antenna 11 receives the transmitted broadcast wave (RF signal) of the OFDM signal and outputs the broadcast wave to the tuner 12 .

[0039] The tuner 12 includes an arithmetic operation unit 12a and a local oscillator 12b.

[0040] The arithmetic operation unit 12a multiplies the RF signal from the antenna 11 and the signal from the local oscillator 12b together, converts the frequency of the RF signal to obtain an IF (intermediate frequency) signal, and the arithmetic operation unit 12a outputs the IF signal to the anti-interference filter unit 13. The local oscillator 1...

Abstract

The present technology relates to a reception device, a reception method, and a program therefor that enable improvement in reception performance when information on a frequency band in which no data is transmitted is known. The reception device receives a broadcast wave of an OFDM signal transmitted from a transmission device at a broadcast station that is not shown. A transmission parameter interpretation unit acquires band information indicating a "no signal" band contained in transmitted control information. An interference rejection filter unit performs filtering at least when a signal with a level higher than a predetermined level is detected on the basis of the band information from the transmission parameter interpretation unit. The disclosed technology can be applied to a reception device that receives OFDM signals, for example.

Description

technical field [0001] The present technology relates to a reception apparatus, a reception method, and a program thereof, and more particularly, to a reception apparatus, a reception method, and a program thereof capable of improving reception performance when information on a frequency band in which data is not transmitted is known. Background technique [0002] Filtering is often used as a technique for reducing interfering signals. For example, in the case where the interfering signal is a signal of an adjacent channel adjacent to the receive channel, a band pass filter or a low pass filter may be used to reduce the adjacent channel signal. As a result, the influence of adjacent channel signals leaking to the reception band can be suppressed. [0003] Furthermore, in the case where the interfering signal is a continuous wave (eg, a sine wave) existing in a specific frequency range or a signal for analog communication existing in the same channel, for example, a notch fi...
