Patent ID: 7860047

Claim:
A wireless communication apparatus comprising: a wireless section that receives a signal transmitted using a wireless communication system based on a first wireless communication standard; and a communication quality estimating section that estimates communication quality in a pseudo manner for the case of transmitting a signal using a wireless communication system based on a second wireless communication standard different from the first wireless communication standard in which frequency band occupied by a wireless signal of the first wireless communication standard is partially or completely overlapped, using a signal for a wireless communication system based on the first wireless communication standard received by the wireless section, wherein: the wireless section receives a known signal transmitted using the wireless communication system based on the first wireless communication standard; the wireless communication apparatus further comprises a reference signal storage section that stores the known signal in advance as a reference signal; and the communication quality estimating section estimates communication quality in a pseudo manner for the case of transmitting a signal using the wireless communication system based on the second wireless communication standard different from the first wireless communication standard in which frequency band occupied by the wireless signal of the first wireless communication standard is partially or completely overlapped, using at least a part of the known signal received by the wireless section and at least a part of the reference signal stored in the reference signal storage section.
