Wireless communication device
First Claim
1. A wireless communication device comprising:
- a first converting circuit configured to decode a signal inputted from an external using a first communication method and to generate first received data;
a second converting circuit configured to decode a signal inputted from the external using a second communication method and to generate second received data;
a first reception start signal detecting circuit configured to receive the first received data and to detect a first reception start signal specified in the first communication method;
a second reception start signal detecting circuit configured to receive the second received data and to detect a second reception start signal specified in the second communication method;
a storing circuit configured to store the first received data in response to detection information outputted from the first reception start signal detecting circuit;
a received data selection determining circuit configured to determine a selection of the second received data only when the second reception start signal detecting circuit outputs detection information;
a receiving circuit configured to receive the first received data, that is outputted from the storing circuit, or the second received data.

Abstract
According to an embodiment, a wireless communication device, which complies with plural communication methods, includes a storing circuit and a received data selection determining circuit. The storing circuit sequentially stores a first received data until the first received data reaches a predetermined data size. When it is assumed that a radio signal complies to a second communication method, a first period is longer than a second period. The first period is a period from a first time when a reception of the radio signal is started to a second time when the first received data with the data size is stored. The second period is a period from the first time to a time when a second reception start signal is detected. The received data selection determining circuit determines a selection of the first received data, when the second reception start signal is not detected at the second time.
