Communication Apparatus, Vehicle Having the Same and Control Method for Controlling the Vehicle

A communication apparatus comprising:

• a band pass filter configured to transmit a communication signal having a frequency equal to or greater than a preselected frequency among communication signals received by an antenna;
• a peak detector configured to detect a peak of a communication signal using a second communication protocol among the communication signals received by the antenna;
• a subtractor connected to the band pass filter and configured to subtract the communication signal using the second communication protocol from the communication signals received by the antenna;
• a switch provided between the subtractor and the peak detector, wherein the switch is configured to operate based on the peak of the communication signal using the second communication protocol detected by the peak detector and transmit the communication signal using the second communication protocol to the subtractor when the switch is in an on-operation;
• and
• a denoise filter configured to remove a noise from the communication signals received by the antenna, increase a sensitivity of a communication signal using a first communication protocol, and remove the communication signal using the second communication protocol among the communication signals received by the antenna by treating the communication signal using the second communication protocol as noise.
