Abstract
A method and an apparatus for concealing an error of an apparatus for receiving an audio frame in a communication system are provided. The includes determining whether the error occurs in a current audio frame that is received from a transmitter, determining whether the audio frame includes a signal that corresponds to a preset specific frequency when the error occurs, setting a gain of the signal that corresponds to the specific frequency to be lower than a preset limit value if the audio frame includes the signal, and concealing the error of the current audio frame based on a previous audio frame of the audio frame in which the error occurs and the gain of the signal that corresponds to the set specific frequency.

A method for concealing an error of an apparatus for receiving an audio frame in a communication system, the method comprising:
- determining whether the error occurs in a current audio frame that is received from a transmitter;
- determining whether the audio frame includes a signal that corresponds to a preset specific frequency when the error occurs;
- setting a gain of the signal that corresponds to the specific frequency to be lower than a preset limit value if the audio frame includes the signal;
- and
- concealing the error of the current audio frame based on a previous audio frame of the audio frame in which the error occurs and the gain of the signal that corresponds to the set specific frequency.
An apparatus for receiving an audio frame that conceals an error in a communication system, the apparatus comprising:
- a receiving unit configured to receive the audio frame transmitted from a transmitter;
- and
- a compensation unit configured to determine whether the error occurs in a current audio frame that is received from the transmitter, to determine whether the audio frame includes a signal that corresponds to a preset specific frequency when the error occurs, to set a gain of the signal that corresponds to the specific frequency to be lower than a preset limit value if the audio frame includes the signal, and to conceal the error of the current audio frame based on a previous audio frame of the audio frame in which the error occurs and the gain of the signal that corresponds to the set specific frequency.
