Abstract
Disclosed is a broadcast signal noise removal apparatus for a vehicle. The present embodiment provides a broadcast signal noise removal apparatus for a vehicle, which decodes a bitstream that is received by an electric vehicle through communication with an external transmission device, then re-encodes the bitstream when an error is detected, then decodes a channel status using a weight, determines whether noise has occurred according to whether the error has been detected, and outputs a bitstream after removing wideband noise of the electric vehicle.
Claims11
An active noise removal apparatus comprising:
- a data reception unit configured to receive a bitstream from a transmission device;
- a deinterleaver configured to deinterleave the bitstream to generate deinterleaved data;
- a decoder configured to decode the deinterleaved data to generate decoded data;
- an error check unit configured to check whether an error is detected in the decoded data;
- and
- an encoder configured to encode the decoded data to generate encoded data and then transmit the generated encoded data to the decoder when an error is detected in the decoded data.
