摘要： A wireless terminal using switchable first and second reception antennas to perform diversity reception of data transmitted from a base station is proposed. The terminal includes an average value calculation unit that calculates an average value of a reception level measurement result of the first reception antenna and a reception level measurement result of the second reception antenna; and a correction unit that corrects the average value calculated on the basis of a predetermined thermal noise level, a received RSSI value measurement result of the first reception antenna, and a received RSSI value measurement result of the second reception antenna.

摘要： A data transfer device having a data transmission side to receive an error detection signal transmitted thereto when an error is detected within data transmitted therefrom. It is decided whether to receive an error detection signal relating to the data transmitted therefrom and retransmission of the data is controlled depending upon the result of this determination. A data receiving side to detect an error in data transmitted thereto, to detect whether there is an error in the data received and, if there is an error in the data received, the data receiving side is capable of receiving data which generates an error detection signal depending upon the degree of the error. Therefore, when an error is detected from transfer data received, it will be possible to re-transfer the data using the address data for the transmission source.
